Hi all, I'm a first time aircraft buyer and have my eyes set on a 1964 M20E. The aircraft has had a bit of an incident in the past (hit a wing and nosed into a ditch in 1990's) but has flown since then. In the pre-buy inspection, I'm having my mechanic be overly meticulous about the wing spar, overall wings, corrosion, and front-end damage inspection. So far, he's come back with a report of:
+ Seeping fuel tanks (blue, green and brown under wings)
+ "cracking and wrinkling" in the lower firewall
+ Crack in paint on the engine mount - want to do further inspection to make sure it's just a surface crack
Plane is a "good deal" but I'm afraid of maintenance adding up so quickly that it soon becomes a lemon.
+ How much of an airworthiness issue is a firewall wrinkle?
+ When is it time to reseal the fuel tanks? Do all of you have some leakage, or is it something that should be fixed as soon as a seep is identified?
Will have more detail tomorrow...
