I have the repairman certificate on the Kitfox I fly since I built it.
If I buy a damaged Kitfox am I legally able to do the major repair and have the work signed off by an A&P or does it need to be an A&I.
Or does an A&P have to do the repairs since I would not have the repairman certificate?
Is this a gray area?
I assume that if I totally rebuilt the aircraft and completed 51% of the construction I could qualify for the repairman certificate but would need to fly off the 40 hours.

Thanks for considering my questions.
The answers will determine if I will consider buying a previously flying project.
