2012 Annual Inspection (iv)

When I spoke with Mike the IA this morning about progress on N631S's annual, he pointed out that both magnetos were due for their 500 hour inspections. This did not require a difficult decision...the work needs to be done. He'll be taking both mags apart, inspecting their innards, and replacing any worn parts.

The Slick magnetos that generate spark for the airplane's ignition system are very simple devices, but subject to wear and tear. Failing to maintain them properly can ruin one's day. This point is made well in this post from the blog of the late and sorely missed Neptunus Lex.

And, by the way, Lex links to a delightful site that explains the design and operation of magnetos in an innovative way. Most highly recommended!

As I was leaving the hangar, Mike was about to start inspecting the seats and seat rails in compliance with an applicable Airworthiness Directive (AD 2011-10-09). This AD is a recent revision to one of long standing that required inspection of the seat rails for wear (Cessna seats having exhibited an unpleasant tendency to come adrift at awkward times in cases of excessive wear). The 2011 version added new guidance covering wear of the roller assemblies that ride on the rails as the seat is adjusted.

A couple of hours later I got an e-mail telling me that there was good news and bad news. The good news was that the rails are fine – within the wear limits specified by the AD. The bad news is that one of the roller assembly housings (see photo) is worn out of limits and will have to be replaced.

The full width of the housing is 0.900" and the maximum gap permitted between the tangs, as annotated on the picture, is 0.440". This one is worn to a gap of about 0.465". It has to go. And Cessna is, it seems, very proud of their parts. A new roller assembly, P/N 1714000-33, will be setting me back $426.66. Fortunately, it's a simple bolt-on installation so there won't be much additional cost for labor. And I can count myself as fortunate that only one roller assembly needs to be replaced. This time.

The only other bit of significant news is that a new muffler (discussed previously) has been ordered and is expected to arrive Tuesday next. That keeps everything on schedule.

2012 Annual Inspection (iii)

There were several things to think about after this morning's visit with Mike the IA and 31 Sierra. A good chunk of the "firewall forward" part of the inspection is done and the only significant issue concerns the muffler. It's a hard life for the muffler, with a constant flow of 1,000+ degree exhaust gas passing through it, so it isn't a surprise when problems develop.

Mike feels (and I agree) that the flame arrestor (the perforated tube visible through the exhaust pipe, at left) is deteriorated beyond acceptability. There are a couple of options available to address this – repair or replace. The decision will be affected by both price and schedule.

Dawley Aviation in Wisconsin is known to do a good job refurbishing these mufflers. They charge $225 if they can reuse the shell and $298 if they can't. The problem is that with a two to three day turn-around, sending the muffler there would require either use of extremely costly overnight shipping or accepting the idea of N631S being grounded through an extra weekend.

You can buy a brand new muffler from Cessna – but they want about $2,000 for it (I kid you not). However, a high-quality aftermarket replacement is made by Wall-Colmonoy. Their Nicrocraft line of exhaust parts is carried by Aircraft Spruce and this unit (part number 0750161-89) can be had for $332.95 plus shipping. This may cost a few dollars more than the repair but the timing will be better.

I had asked Mike to have a look at the connectors for the flow transducer (seen at left) that feeds its signal to the Shadin fuel flow computer. For about the last year, the unit has periodically suffered from erratic behavior. But it would recover after a few hours and when it is working it works perfectly. I've acquired a replacement transducer, but I'm reluctant to remove the old one while it's working. There appear to be no problems associated with the wiring, so we'll cover it back up and wait for it to fail. Fortunately, it's not essential for flight and it's readily accessible with the lower cowling removed so it makes sense to wait.

Finally (for today), we are replacing the plastic end caps on the right horizontal stabilizer and the right side of the elevator. A few "smoking rivets" have shown up there and Cessna has a service bulletin (number SEB03-1) covering the area. It calls for increasing both the number and size of the rivets. But the plastic end caps are cracked and likely not salvageable, so they'll be replaced. The image at left is from the service bulletin, showing the area in question.

I'll be stopping off at the airport tomorrow morning, of course, to see what new things are in store.

2012 Annual Inspection (ii)

This morning I stopped by the hangar to visit N631S, collect the various loose items for storage, and see how the inspection was progressing.

Before anything was taken apart, Mike the IA did a pre-maintenance run-up and found no discrepancies. The airplane is decowled, the old oil drained, and the main gear fairings are off. The upper spark plugs have been pulled; they look good. Work continues on opening the inspection covers and removing the interior.

The results of the engine's cylinder leakdown check (i.e., the "compression test") look quite nice. Mike checked the cylinders for leakage as instructed by TCM Service Bulletin SB03-3. Last year, one cylinder, #2, was not very tight. It tested at 48/80 psi on a day when the minimum acceptable value based on the standard orifice was 46/80. This year, on a day where the minimum acceptable value was 48 psi, it performed better. From the logs, here are the compression values at each annual inspection since 2007 (charted below):

Obviously, cylinders #2 and #4 were having a much better day this year than in 2011. N631S's engine is now at 1567.4 hours since its last major overhaul and oil consumption never exceeds 2 quarts during each 50 hour oil change interval. I anticipate that no surprises will arise from spectrographic analysis of the used oil, or from the visual inspection of the filter media or from the borescope inspection of the cylinder interiors. It looks to be a healthy engine and there appears to be every chance that it will happily run well beyond the nominal 2000 hour TBO period...at least I hope so!

As usual, I'll be stopping at the hangar tomorrow morning to see what items of interest Mike has found today.

2012 Annual Inspection (i)

Once again it's time for N631S's Annual Inspection. Last year the Annual was 'signed off' early in April so this year's inspection could have started as late as April 30. But I am otherwise engaged next weekend and the oil is nearly due for changing so this seemed like a good time to turn the airplane over to Three Wing Flying Services for about two weeks.

Actually, I've asked that they target Thursday,March 29th as the completion date. That will let me get a test flight in and have the next day, Friday, available for resolving any lingering 'squawks' prior to an IFR flight back to the DC area.

There's an administrative change in how the work package is being managed this year and I think it's a good one. As I've noted before (for example, here), the Annual Inspection is neither more nor less than is specified in Appendix D to Title 14 CFR 43. Usually, however, there are a number of maintenance actions that get accomplished in conjunction with the inspection but that are charged for separately. Three Wing has chosen to offer a "Flat Rate Package" encompassing the Annual Inspection and the associated Maintenance items for one fixed price. I looked at the proposal and compared it with the actual costs of N631S's last three Annuals, and concluded that the Package was reasonable and fair.

So, we've agreed that items beyond the inspection, estimated to require 13.9 man-hours, will be part of the Flat-rate Package. These include the engine compression check, the oil change, and servicing of spark plugs, magnetos, flight controls, landing gear and wheel bearings. Assorted filters and screens will be cleaned and serviced, the prop will be dressed and painted and the ELT will be inspected. Add the estimated 17 hours for the actual Annual Inspection, and the package totals 30.9 labor hours. At a shop rate of $86/hour that means I've spent $2,657.40 before any emergent work items revealed by the inspection are addressed. (I think I already know about a couple of those, to be discussed in coming posts.)

If all went according to plan, today Mike the IA did the maintenance run-up, checked the cylinder compressions, and started to open up the airframe. More on all that tomorrow.

Something Happened

Something happened on this day thirty-five years ago in Wichita, Kansas. A Cessna Aircraft Company production test pilot named Jim Ballard picked up a blank Aircraft Log. On the cover next to the 'N' he entered '631S' and next to 'SERIAL NO.' he wrote '18265554'. Then he turned the page and on the first leaf, next to 'Record of' he entered 'Cessna 182Q 18265554 N631S'. On the next line, next to 'With Engine' he wrote 'Continental O-470-U 465712'. Then he went out on the ramp at Wichita's Mid-Continent Airport to meet the machine whose birth as an airplane he was about to facilitate.

Jim certainly performed a careful pre-flight inspection, then he climbed into the cabin and started the big Continental six and, with concurrence from the tower, taxied for departure. Senses alert for any sign of defect or maladjustment, he took the machine off the ground and into its natural element. For 1.3 hours he checked and verified, in accordance with his production test check-list, the readiness of this machine to be sent on to its new owner-pilot. Then he landed, back where he'd begun.

After shutting down he opened the Aircraft Log once again and turned to the first page for the recording of flight data. He filled in the year, '77', and the day, 'Mar. 18'. Under From, 'Ict' and under To, 'Local'. Nature of Flight is 'Test', and Duration of Flight is '1.3'. And then he signed the column labeled Signature of Pilot...'Jim Ballard'. N631S had passed its test.

Thirty-five years later...two engine overhauls later...nine owners and 4,235.2 tach hours later...N631S continues to pass each test, to be a machine admirable in every respect. As the current caretaker, my gratitude flows to Jim Ballard and to every owner and pilot who has cared for and worked with this airplane in the intervening years. I'll try to be worthy of the airplane you've entrusted to me.

Now for Some Real IFR! (cont'd)

This will be an update on the flight that was anticipated in yesterday's post. Yes, I did manage to get N631S wet...and no, not so very wet after all.

This was the METAR on offer for our departure from KBDR:

 
KBDR 161952Z 09005KT 10SM OVC005 07/04 A3013 ...

Wind out of the east at five knots, good visibility and a low overcast. We took off from Runway 6 and entered the base of the cloud layer at 500 feet, as advertised, then emerged from the tops at 2,400 feet into bright sunshine. And that was the last cloud we saw for quite some time.

Looking ahead an hour and a half later, from somewhere near Lancaster, the on-board NEXRAD display showed showers in the vicinity of our destination, KVKX. I watched them for a while and they just weren't moving. Low level winds were very light and there was nothing to motivate those showers to 'move along.' But there didn't appear to be any reason for concern. The METARs from Washington National (KDCA) and Andrews AFB (KADW) showed light winds and good visibility. I thought I might even get away with a visual approach at KVKX:

 
KDCA 162252Z 00000KT 5SM BR BKN100 BKN200 14/12 A3015 RMK AO2 RAE10 SLP209 P0000 T01440122

KADW 161955Z AUTO 08003KT 9SM -RA OVC028 14/11 A3015 RMK AO2 RAB1918DZE1918 CLDS LWR SLP212 P0000 T01410113 $

The patch of showers never did depart the area and the view out the right-side window as I flew south from Baltimore to the Nottingham VOR (OTT) did not give me a warm feeling about the visual approach. So I asked Potomac Approach for vectors for the RNAV Rwy 6 instrument approach which they cheerfully provided. N631S and I flew through some light rain on final but when we landed the runway was dry.

Would I have been able to complete a visual approach without any problem? In all likelihood, yes. Was asking for the RNAV approach the conservative thing to do? You bet!

Now for Some Real IFR!

The cold temperatures prevailing aloft for the last few months have ensured that most flights conducted under Instrument Flight Rules (IFR) have actually proceeded in Visual Meteorological Conditions (VMC)...i.e., there's been ice in them clouds! So today I'm looking forward to actually getting N631S wet! I'm planning a departure a bit after 20Z from Connecticut and expecting a route over eastern Pennsylvania then down over Baltimore and into the DC area.

The key to this is a really big bubble of warm air over the middle of the country, working its way east. The plot at left shows the freezing isotherm for around 9,000 feet MSL projected to be well to the north of my flight path. (You can click on the image to make it bigger.) So whether there are clouds in my way, or not, doesn't matter much. I can be fairly certain that icing won't be an issue today.

Of course, you do have to take off and land. For those purposes, the forecasts for my departure and arrival airports are fairly benign. Here are the current Terminal Area Forecasts (TAF's):

 
KBDR 161325Z 1613/1712 12009KT P6SM OVC015 
     TEMPO 1613/1615 4SM -DZ BR BKN006 OVC010 
     FM161600 VRB05KT P6SM BKN010 OVC030 
     FM162300 VRB04KT P6SM SCT025 BKN040 
     FM170400 VRB03KT 4SM BR SCT020 OVC040 
     FM170700 VRB03KT 2SM BR BKN020
        
KDCA 161122Z 1612/1712 04007KT 4SM BR OVC006 
     FM161400 VRB04KT P6SM BKN008 OVC100 
     FM161500 VRB04KT P6SM BKN060 OVC100 
     FM161700 20005KT P6SM VCSH BKN050CB OVC090 
     FM162100 VRB03KT P6SM -SHRA BKN040CB OVC100
     FM162300 VRB03KT P6SM FEW040 OVC100 
     FM170300 33004KT P6SM BKN100

The pertinent forecast lines are highlighted in red. For departure from KBDR it looks like I should expect light winds, good visibility, and a broken ceiling at around 1,000 feet, overcast above. Arriving in the DC area I can look for light rain showers beneath a broken 4,000 foot ceiling of cumulonimbus (CB). The presence of CB's in the TAF implies a chance of convective activity, but not enough for thundershowers to be part of the forecast. And, as it will be getting on toward the valid time for the next line in the forecast (from 23Z) as I get there, conditions may be improving.

It looks like it should be a good flight.

Are you Sinistral? (cont'd)

Two weeks ago I posted a request for pilots visiting this blog to participate in a survey, asking whether they were "left handed." I recognize (now, as I did then) that this is thoroughly unscientific. There is much more to handedness (or laterality or chirality) than which hand you use to pick up a pen. Just speaking for myself, I would be classified in a more sophisticated study as mixed-handed or cross dominant. But the question under consideration is: does the pilot community as a whole reflect the "handedness" of the general populace? Perhaps the survey result would be an indicator.

I leave it to you to decide whether the result is significant. Here's what emerged:

• Total respondents: 91
  
• Respondents self-identified as "left handed": 30
  
• %'age of "left handed" respondents: 32%
  
• %'age of the general populace "left handed": about 10%
  
• Factor by which left handed pilots exceed general incidence of left handedness: about 3.2X
  

Actually, I'm surprised, having expected that the pilot community would be "handed" about like the general populace. Well, maybe not so much!

As vulnerable as this query is to confounding factors, it's hard to imagine a scenario that would explain away the entirety of excess left handedness among pilots reflected in the data. I have to conclude that pilots are, to a significant degree, more often left handed than "normal people."

A Dark Cold Day

At about 0915 PST last Tuesday, Capt. Carroll 'Lex' LeFon, USN (Ret'd), died when the IAI F-21A Kfir that he was piloting crashed just inside the west gate of Fallon NAS in Nevada. I infer that he was returning from a sortie flown on behalf of his employer to provide "dissimilar type" aggressor aircraft services to the Navy so our young fighter pilots will be better equipped to stay alive and prevail in future encounters. As far as I'm concerned, Capt. LeFon died in the line of duty, serving our country.

There was another side to Lex. He maintained a blog at Neptunus Lex where he wrote eloquently of military affairs and the sea and politics and life. And flying. He wrote with an immediacy that pulled the reader into the cockpit and into the reality of flying the fast-movers. His writing could get your heart beating faster, could get your blood flowing. So I ignored (with difficulty) his politics and reveled in his exquisite tales of the airman's world. (The blog will be there; go on over and read his work.)

Lex retired from the Navy in 2008 and thought to make a second career working at a desk. But that ability was not given to him, so he went back to flying jets. Specifically the Kfir, which is sort of a tinfoil airframe wrapped around a roaring J-79 afterburning turbojet. He had to have loved it.

He also loved the poetry of William Butler Yeats. And so these words, taken from W.H. Auden's "In Memory of W. B. Yeats", seem to serve:

He disappeared in the dead of winter:
The brooks were frozen, the airports almost deserted,
And snow disfigured the public statues;
The mercury sank in the mouth of the dying day.
What instruments we have agree
The day of his death was a dark cold day.
- - - - -
But in the importance and noise of to-morrow
When the brokers are roaring like beasts on the floor of the Bourse,
And the poor have the sufferings to which they are fairly accustomed,
And each in the cell of himself is almost convinced of his freedom,
A few thousand will think of this day
As one thinks of a day when one did something slightly unusual.

What instruments we have agree
The day of his death was a dark cold day.

Carroll "Lex" LeFon, Capt., USN (Ret'd)

Book Review: "Flight for Control" by Karlene Petitt

The world in which Karlene Petitt's debut novel, Flight for Control, takes place looks very much like our own. It's a world where the airline industry, an important part of the fabric of society, is operating under severe economic and operational pressure...much like it does in our world, but a little...just a little worse.

"Flight for Control"
by Karlene Petitt; 382pp.
Jet Star Publishing, 2012

It's a world where independent agencies like the National Transportation Safety Board (NTSB) come under the extralegal influence of an increasingly out-of-control Homeland Security complex...to a degree perhaps slightly greater than we see in our world.

And it's a world where good men and women strive ceaselessly against these pressures while seeming never to make progress or see improvement in their personal and professional lives. And where, perhaps, they wind up vulnerable to the schemes of a charismatic and Machiavellian figure who promises drastic action to solve their intractable problems.

The narrative is focused on an ex-NTSB accident investigator who left her career for family-track reasons. But circumstances surrounding a series of airline mishaps draw her back into the fray. As it happens, she is married to an airline Captain who is running for a leadership position in the pilots' union on a confrontational platform – the classic "Man on Horseback." There is, of course, much more to his plans than can be seen on the surface.

The plot hurtles forward, keeping the reader engaged. The author, a pilot who flies Airbus A330's on international routes for a major air carrier, keeps the aviation side of the story "shiny side up" to the gratification of the airplane-savvy reader. The dialog is crisp and the characters well-developed and believable.

(Required caveat: The tale includes several scenes where adult characters do adult things with each other. Probably not what you want to give to your aviation-smitten thirteen-year-old...unless you have a very mature thirteen-year-old.)

I found this book hard to put down (as in, "Hey, it's only 11:30 – one more chapter won't hurt me..."), and it left me looking forward to meeting the protagonist again in a sequel.

In several dimensions, the world of Flight for Control is our world, writ large. The question becomes whether this world is some intriguing alternate reality – or our own future. At the end of the book the author includes some "Questions for Discussion" regarding crew-related challenges that confront the aviation industry. We need viable answers to these, or some aspects of the story may become too real for comfort.

Send in the Drones? (cont'd)

I guess we have to talk about this. A post appeared on this blog 20 months ago, saying in part:

..we are being prepared for the day, not very far off, when we will be sharing the skies with Unmanned Aircraft Systems (UAS), also known as drones or remotely piloted vehicles (RPV's)...

As of Valentine's Day, when the President signed the recently passed FAA Reauthorization Act (Public Law 112-95), that day is upon us. There are some who are evincing surprise at the developments in this arena. I can only surmise that they have of late been asleep.

Section 332 et seq. of P.L. 112-95 has quite a lot to say on the topic of Unmanned Aircraft Systems. To begin with, the Law requires that on or before the 14th of May of this year the Secretary of Transportation must enter into agreements with "appropriate governmental agencies" that streamline the issuance of waivers or authorizations to operate "public unmanned aircraft systems" in the National Airspace System [P.L. 112-95 Sec. 334 (c)(1)].

The contemplated agreements must provide for expedited review, approval action within 60 business days, and expedited appeal in the event of disapproval. These agreements will, further, permit one-time approval of "similar operations carried out during a fixed period", and allow a "government public safety agency" to operate UAS's weighing up to 2 kg. within the operator's line of sight, up to 400 feet AGL during daylight conditions in uncontrolled airspace outside of 5 statute miles from any airport, heliport, etc.

One suspects that after about mid-August, anyone that flies low in uncontrolled airspace (agricultural applicators? pipeline patrols? balloonists? transiting helicopters?) is going to need to keep a sharp lookout for little 4 pound camera carriers buzzing around to help the constables search for marijuana patches, meth labs and undocumented immigrants. Will it be the responsibility of the operators of these devices to "see-and-avoid" other traffic? That would seem to be a rule-making matter,but the expedited schedule allows little time for orderly rule-making.

Once that little piece of business is under control, P.L. 112-95 gives the Administrator of the FAA until the 12th of August to set up a program of, at most, five years duration, that will establish six "test ranges" for the integration of UAS's into the National Airspace System (NAS) [P.L. 112-95 Sec. 332 (c)(1) et seq.]. In selecting locations for the test ranges, the Administrator is required to consider "geographic and climatic diversity", "ground infrastructure and research needs", the views of NASA and DoD, and no doubt (though not explicitly required), the location of the districts represented by the relevant congressional committee chairs.

The program's goals are fairly ambitious:

• To "safely designate airspace" for integrated manned and UAS operations;
  
• To "develop certification standards and air traffic requirements" for UAS's;
  
• To "coordinate and leverage" NASA and Dod resources;
  
• To "address both civil and public" UAS's;
  
• To coordinate with NextGen;
  
• To verify the safety of UAS's and related navigation procedures before integration into the NAS.
  

With these pilot projects established, no doubt to the financial pleasure of the usual suspects among DoT contractors, the cognizant managers will need to hustle to comply with the next requirement of P.L. 112-95. The act gives the Secretary until November 10th of this year to develop a "comprehensive plan to safely accelerate the integration of civil [UAS's] into the [NAS]." This plan is to be formulated "in consultation with representatives of the aviation industry, Federal agencies that employ [UAS] technology in the [NAS], and the [UAS] industry." [P.L. 112-95 Sec. 332 (a)(1) et seq.] (One wonders whether the GA community will have a seat at that table.)

The Act is fairly explicit on what it expects this "comprehensive plan" to comprehend, among other things (emphasis added):

• The anticipated rulemaking that will (i) define operating and certification standards for civil UAS's, (ii) ensure that UAS's incorporate "sense-and-avoid" capability, (iii) establish standards (including registration and licensing) for operators and pilots of UAS's;
  
• To project methods to enhance the technologies needed to achieve safe and routine operation of UAS's in the NAS;
  
• To recommend a phased-in approach to the integration of civil UAS's in the NAS;
  
• To project a timeline for this phased-in approach;
  

The plan is required to provide for the "safe integration" of UAS's into the NAS "as soon as practicable, but not later than September 30th, 2015."

The Act requires that the integration plan be forwarded to congress within a year (i.e., by February 14th, 2013), and that also by that date "the Secretary shall approve and make available in print and on the Administration’s Internet Web site a 5-year roadmap for the introduction of civil unmanned aircraft systems into the national airspace system...," said roadmap to be updated annually.

And, finally, the Act requires [P.L. 112-95 Sec. 332 (b)] that:

• "not later than 18 months after the date on which the (integration) plan...is submitted (i.e., at latest, by August, 2014)...the Secretary shall publish...a final rule on small (i.e., 25 kg or less) unmanned aircraft systems that will allow for civil operation of such systems in the national airspace system...",and;
  
• "a notice of proposed rulemaking to implement the recommendations of the (implementation) plan (presumably to encompass UAS's other than "small")...with the final rule to be published not later than 16 months after the date of publication of the notice (i.e., not later than December, 2015)."
  

So let us summarize the timeline:

• May, 2012: Agreements with government agencies on waiver procedures for operating public UAS's (of max. wt. 2 kg) in the NAS;
  
• August, 2012: Likely first operations of public UAS's in the NAS under waivers;
  
• August, 2012: Establish "test ranges" for development of UAS technologies and methods needed for integration;
  
• February, 2013: UAS Integration Plan due to Congress; Roadmap published in print and on-line;
  
• August, 2014: Deadline for final rule for civil operation of "small" (i.e., 25 kg.) UAS's in the NAS.
  
• December, 2015: Deadline for final rule for civil operation of all UAS's in the NAS.
  

The planning and rulemaking processes set in motion by the recent act of Congress deserve close watching, particularly as each key milestone is reached. It's going to get busy up there over the next few years!

Are you Sinistral?

Over on an on-line forum that I frequent, a question has arisen about whether the prevalence of left-handedness in the pilot community matches that in the general population.

So, a somewhat unscientific experiment. Could I ask visiting pilots (only, please), to register their "handedness" (one vote each please!) on the widget at the top of the sidebar at right. I'll say up front that I expect to see no real difference between pilots and folks in general, but hey, that's why we do the experiment!

Nothing to Report

We approach the end of winter, and it has been a really remarkable season in the Northeast. (Meteorological winter is defined to encompass the three calender months having the lowest mean temperatures, i.e. December, January and February – at least here in the northern hemisphere.) We're 10 weeks into that span with only three more weeks to go. And flying over Maryland, Delaware, New Jersey, New York and Connecticut on Monday, I saw no evidence of snow cover at all. None. Zero. That's remarkable.

Since the season began on 1 December, N631S and I have been able to make the trip between KBDR and KVKX seven times in each direction, of a possible ten. That's a much better dispatch rate than we've achieved in the previous couple of winters. (At left, the flight southbound for Christmas weekend.) There was one weather related diversion in December, recounted in these two posts, but that was a result of fog, not the wintry stuff endemic to the period.

And it's been warm. Out of seven Friday afternoon departures from KBDR since 1 December I've only once needed to have my friends at Three Wing Flying Services hook up N631S's Tanis pre-heat system – meaning that every other time the temperature was above 40ºF. I've used the pre-heat system a few times of a Monday morning, after a 6:00 AM arrival at KVKX, but never due to anything lower than about 30ºF. In short it's been quite mild.

Of course I'm not complaining. A look into my logbook for the last ten weeks shows many entries that are variations on the theme: "IFR in VMC; uneventful." And of course uneventful is good! But it doesn't provide a great deal of fodder for posts on this blog having the potential to entertain and enlighten my occasional visitor. Still, I'll take the deal.

There are three weeks left in the season and almost certainly I'll find myself on Amtrak a time or two. And then March may be anything but benign...time will tell. However, at the risk of appalling my friends from the midwest, the Mountain States, or Pacific northwest (who have had, of late, far more entertaining weather) I can say that the Winter of 2011-12 already belongs in the "Win" column and I'll hope for one just like it next year.

Book Review: "The Map of My Dead Pilots" by Colleen Mondor

I have no standing to remark on a book about flying in Alaska. I have not endured the awful cold, withstood the cutting wind, peered into the frozen fog. Like everyone else, I've seen the photos – watched the films – read the stories. But of course, there are stories and there are stories.

"The Map of My Dead Pilots"
by Colleen Mondor; 242pp.
Lyons Press, 2012

Early in the 1990's, with a degree in Aviation Management and a need to expand the boundaries of her life, Florida-girl Colleen Mondor went to Alaska and took a job as a Dispatcher for an air-charter company (what aviators refer to as a Part 135 operation) in Fairbanks. For seven years she scheduled aircraft, typed manifests, wrangled customers, pitched in on the ramp and soaked up the reality of Alaskan aviation. And she befriended pilots and got to know them, and watched as they departed in ragged, challenging Alaska weather. And dined and drank with them when they returned. And drank with their friends when they didn't.

She earned a graduate degree in History while she worked in Alaska, studying the origins of Aviation in the Far North. She learned about Eielson and Merrill and the Wiens and other legendary names, not just accepting the stories that sustain the legends, but delving into contemporaneous sources from the 1920's.

She's blended this historical knowledge with the perceptions derived from her personal experience, allowing it all to simmer for a decade, and has now given us something more than a mémoire. The Map of My Dead Pilots has a tremendous immediacy and the ring of truth. It's for people who have shivered in Alaskan cold to comment on the accuracy of Ms. Mondor's details, but she gets the airplane stuff spot on. This is a hard book to put down.

And, oh yes, the lady can write. Within the bounds of fair use, here's a taste:

"But then there was this.

When Henry Smoke passed away in the hospital, his family asked the Company to send Tony home with the body. They wanted a pilot who knew Henry and could call him by name. Tony had been flying in and out of the Upper Yukon for years, and Henry was the Company's agent in Stevens Village forever. The two of them went way back. When Tony landed in the Navajo, most of the folks from Stevens and the surrounding villages were on the ramp waiting for the plane. They unloaded the heavy, ornate casket, placed Henry down in the back of a waiting truck, and then drove slowly away. Tony waited until he was the only one left at the airport before he started up the engines. He said later he wanted to preserve the quiet for as long as possible – he wanted to keep the ground holy.

Tony was not a religious man, but there you go. For Henry Smoke, that was the word he thought of.

He said later he was glad he took that flight, that they asked for him. He packed Henry's flight away with the ones to keep with him, and when Tony left Alaska he had well over ten thousand hours of flight time, but Henry Smoke was the only body he knew by name."

The Map of My Dead Pilots is an elegant mémoire of the author's years spent in the service of Alaskan commercial aviation. Its stories are informed by her knowledge of the historical background. But the book is more than a compendium of interesting stories.

It becomes an exploration of the variability of memory, the plasticity over time of historical information, and the malleability of stories depending on the needs of the teller and the audience. The author's tale is one of striving for the truth and learning that truth can only be approached as an asymptotic limit.

There are stories and there are stories. Ms. Mondor tells her stories as accurately as memory and circumstance allow, and she leaves the reader (I believe) with an understanding of the truth of flying in Alaska.

Happy New Year (with a look back)

This is the third year that I've used this post title on 31 December. A year ago, I looked back on 2010 in this post, and a year earlier I reviewed 2009 in this one.

N631S finished the year with 4,207.3 hours on the tach, having flown 175.8 hours in 2011. That's really very close to the 2010 total of 177.9 hours. I made the round trip from KVKX in Maryland to KBDR in Connecticut and back 34 times this year, three and a half fewer than last year. That's in addition to a trip from the DC area down to the Carolina Outer Banks, thence inland to Nashville and back to home plate.

I logged 10.0 hours in actual IMC (instrument meteorological conditions) this year, compared with 2010's 12.9 hours. The weather has been good! The down-side of this is that this year's total of 10 instrument approaches flown in actual conditions is down from last year by four. Time logged as night this year was 10.2 hours, not materially different from last year's 9.2.

Since N631S came to us in 2004, it has been a remarkably reliable machine. But age may be catching up with it a bit, for this year has been – shall we say – maintenance intensive:

• In February, the alternator was replaced.
  
• During the Annual Inspection in April, the voltage regulator was replaced.
  
• Also at Annual, the 121.5 MHz ELT was replaced.
  
• In May, replaced the pilot's Push-to-Talk switch.
  
• In July, replaced the left fuel bladder.
  
• In November, replaced the switch, circuit beaker, flasher and lamp for the rotating beacon.
  
• In December, a new battery, and tagged "Inop" the activation switch for the GPSS module.
  

And the last item in the above list calls for a mea culpa from me regarding the recent absence of posts here. The December weather has been remarkably cooperative, allowing flight from KBDR to KVKX on the Friday before Christmas (with due attention paid to potential icing), then a return to KBDR after the holiday weekend, and finally, back to the DC area this Friday past to end the year. Each of these trips was completed uneventfully. Let me just offer this video clip, collected over central New Jersey whilst headed south at 6,000 feet on the 23rd, just above the solid, cold and icy undercast. As always, ATC was concerned and helpful:

And finally, may I wish all who may visit here a healthy, prosperous and safe 2012.
