Hi fellow pilots! This is my first post, but I have been a 1965 M20E owner for about 15 years. I have participated in owner assisted annuals every year with several excellent A&P/IA's. I also have Aerospace and Mechanical engineering degrees and a fairly extensive shop. This year I was very surprised to discover that the nose gear shock mounts were placed in service in 1970! And the mains last updated in 1990! So quite possibly these might be the oldest and hardest shock disks in the fleet. Needless to say, the airplane is standing much taller. So the advice to find an experienced Mooney A&P shop is certainly justified. I'm looking forward to greased landings from now on....
