We're not going to return the airplane to service with the fairing in this condition. A new fairing will be ordered today. If we can get it in time, it can be installed in "green" condition (i.e., unpainted) to support getting N631S back on the flight line for a trip to the DC area on Friday. It's not a big deal to take the fairing off again for painting a week or two down the road.
The lesson learned here for me is that I need to get down on the ground periodically to closely examine the underside of N631S including all of its appendages. Perhaps that ritual needs to be added to my SOP for oil changes.
Other than the gear leg fairing, nothing of real significance has emerged. Four of the six upper spark plugs were beyond serviceable limits and the other two were marginal so we'll replace all six with the two passable plugs going into the toolbox for use if a plug fails on the road. These are massive-electrode plugs; the lower ones are fine-wire plugs and they're doing fine.
Finally, the portable O2 bottle has survived hydrostatic testing and can be recharged and put back in the airplane. In case you were wondering, testing an oxygen bottle costs $26.50.
