All facts given, what are the top three service problems you see in maintaining a Mooney?
Aside from the fact that you need to locate a true Mooney specialist to service your Mooney about once a year, there are about 8-12 common problems, but considering Mooneys over say, 10 years old I would list the following: 1) Landing Gear being significantly (dangerously) out of adjustment and/or nose gear truss and trunnion being worn beyond Service Manual Specs. 2) Fuel Tank seeps (especially in the wing root/cockpit areas) to the point of requiring service. 3) Poor engine compartment maintenance such as worn hoses, harness, exhaust systems etc. And if there is a 4th, it would be previously un-identified corrosion in a vital areas which if caught (and treated) soon enough isn’t a big problem. Remember, corrosion is the Mooneys main enemy, not calendar time and especially not even excessive flight time. or total time.
