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