What are the guideline on reusing parts off a de-registered aircraft ?  Can you use the fuselage frame from an experimental aircraft that has been de-registered along with new wings, engine, instruments etc.( well exceeding 51%) and apply for an airworthiness certificate as a new aircraft ?   Local FAA doesn't have an answer.

Unless you can prove that it was amateur built, you won't get "Credit" for the part in your 51% tally.  In some cases it is not easy to prove that these parts were amateur built.  That's the rub. 


As far as salvaging small parts from a certified or an experimental aircraft, these are OK.  However, it is very UNwise to reuse fasteners such as nuts (and especially nutplates), bolts and screws, these are such small cost items that it is impossible to justify the difference in cost relative to the risk.  Even inspection cover screws on my certified aircraft just aren't worth saving.  I just by 100 to 200 of each size (8-32 and 10-32) and replace them ALL at annual.
