Q:  My 337 was rejected by the FAA Aircraft Registry.  Why?

A:  The likely reason that this could occur is if your registration information in Blocks 1 and 2 of the 337 did not match FAA records.  We always suggest that you copy this information directly from your airplane's Certificate of Aircraft Registration, FAA Form 8050-3.
