The public federal record on N41GP, read the way a buyer, lender or insurer reads it: FAA registration, prior tail numbers keyed on the serial number, reuse of the tail number, recent registry filings, and the NTSB accident record under this and every earlier registration.
Valid registration to Homan Alan, an individual, certificate issued May 14, 2024, expires May 31, 2031. No fractional interest recorded. [1]
Experimental certificate for amateur built; the FAA file gives no certificate date and no manufacture year. [1]
No earlier tail number is recorded against serial 400 for this model in the deregistered file. [2]
N41GP was previously assigned to 2 other aircraft: Patterson Glen P GYROBEE (serial 013936, cancelled March 14, 2018); Christen Industries Inc PITTS S-2B (serial 5206, cancelled February 18, 2000).
