Hi VMCDemo,
Slightly off topic, but if you are considering buying a Chipmunk check the maintenance records for the undercarriage mounting x-ray inspection TNS-165.
This is a repeat inspection (every 6 years I think), most are cracked but only need to be monitored for crack propagation. I no longer have a copy of the TNS so I can't tell you what the limits are.
There is also TNS-157, another 6 year repeat x-ray inspection on the tailplane structure front spar joints, I don't recall ever finding one cracked but it does require removal of the tailplane and elevators as a complete assembly to carry out the inspection.
Neither of the above would be a deal breaker but it would be better to check they've been done recently to avoid any unexpected costs.
Good luck with the purchase !
And if you do buy it, we want photos
