These numbers belong to the same aircraft, as far as my research shows. The c/n filed with the FAA seems to be the problem. This bird was originally AT-6D 42-84503, then to SNJ-5 43942. The profile for N3931Z uses the c/n, while N21&RK uses the USN BuNo. Since N3931Z is no longer an active registration, can that one be fixed with the c/n to link the two?

Just now we cannot make profile alterations which conflict with the FAA records.

May I suggest you file suitable comments to be added to the comments section of the profiles in question.

I thought by being an obsolete record it could be edited. I'll post a comment on it.
