I always kinda figured that a factory overhaul was the "best". But at the hangar some folks are skeptical about a factory reman, and seem to have the impression that the process is more assembly line with non A&P workers doing the majority of the work with a sign off at the end. Seemed a little out there to me that the company that built it isn't as good at rebuilding them than Joe A&P at the airport. So, what's better?
