I just had a cylinder repaired in my Cessna 150 ($400 for the contract work
and probably $300 for my A&P to remove and install) for the sole reason that
the pressure was 55/80. The engine ran fine and displayed all the normal
zest and pep that we associate with a Cessna 150. I didn't want to have the
work done at all.
Three years ago I had a cylinder replaced since the pressure was 26/80. Big
surprise to all of us since the engine ran very smoothly. However, I had no
problems authorizing that repair.
I was told in no uncertain terms that the aircraft is considered unairworthy
by the FAA if the cylinder pressure was under 60. I'm afraid that it's more
than just a magic number -- it's the law. At least according to my A&P for a
Cessna 150.
Any A&P's out there care to comment? Was my guy right?
