I am restoring a Chief that had the N number changed in the 60's. The new number doesn't contain a C after the N as they are not used anymore. Can I still use NC when displaying the newer N number on the aircraft?
FAR 45.22 seems to elude to the fact that I can.
Thanks!

NC Number
I just went through the same thing with my Fleet. The previous owner had the NC on it, but my IA insisted that it had to be changed to just the N. Upon further investigation, he found that all records of the aircraft have to be referenced to the N number. However, older aircraft are allowed to "display" an NC on the aircraft. I don't remember how old the plane has to be, but the Aeroncas we are flying easily qualify.

NC3469E - NC markings

The FAA allows you to use the NC designation on our vintage airplanes for nostalgia reasons - It is legal - However the real number for the airplane on your registration will leave the C out such as: NC3469E is really N3469E.
