German guy
Cleared for Takeoff
The pre-buy inspection revealed that it is not documented that the AD94-05-05R1 for the Continental O-300 of the plane we want to buy had been complied with.
The AD requires that when a cylinder is removed, the cylinder rocker shaft bosses need to be inspected.
All cylinders had been removed / replaced since the AD came out, no log book entry regarding the compliance with the AD was however made.
The broker, who represents the seller, tells me that the guy who did the annual also automatically confirmed the compliance with all ADs by signing it off and that we could legally fly the plane at least until the next annual. Most mechanics would however assume that when the cylinders had been pulled, the AD had also been complied with.
I did some research and understand that the compliance with an AD needs to be specifically stated in the log book.
So, what do you think? The engine has ran 1500 hours and was overhauled 40 years ago. I would think that the efforts to do the inspection of the cylinder rocker shafts would be so high that it would make more sense to do a complete overhaul instead!?
