Hi chaps,
I'm reasonably comfortable with the engineering process of my problem, but am completely out of the loop on the legal process.
I have a UK registered Annex II CofA light aeroplane, very old, which has a condemned oil cooler due to severe core leaks. The aeroplane is 60+ years old with the original engine, not a common type.
I'm chasing a possible source of a new oil cooler with paperwork, but suspect that I only have a 50% chance of success there.
So, if I fail, it looks like I'll have to design a mod to fit an alternative oil cooler to the aeroplane. As an engineering process, I'm comfortable with that - however...
... can anybody explain what I need to do to get that mod approved at the moment whilst keeping the aeroplane on a CofA?
(Alternatively, if anybody happens to have a serviceable oil cooler with release paperwork for a Franklin 6A4-165-B3 engine, or knows somebody who can raise expired oil coolers from the dead, I'd love to hear from you!).
