This is my first trip into the homebuilt world. I'm probably going to
buy a 90% complete project, and want to know if there will be any
paperwork hassles I'll have to jump through to get it registered.



Get a tall stack of detail photos for documentation.


I realize I won't have the repair authorization as I did not build 51%
of the plane, but what should I look for as far as documentation from
the current owner and what will the FAA expect to see from me?

Apply for the repairman's certificate when it comes time to
do all the paperwork. The so-called 51% rule does not apply there.

I have AC 20-27F, but during a very quick glance-through I didn't
notice any specific mentions. Any help appreciated!

Study it in detail.

Have fun!
