The public federal record on N4577C, 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 Koinzan Seed And Flying Service INC, a corporation, certificate issued October 22, 1987, expires December 31, 2028. No fractional interest recorded. [1]
The airworthiness certificate on file is dated February 22, 1956, 3 years after the 1953 manufacture year. A re-issued certificate commonly follows export and re-import, a rebuild, or a return to the register after cancellation. The cause is documented in the FAA aircraft records file, which the full report obtains. [1]
No earlier tail number is recorded against serial 25521 for this model in the deregistered file. [2]
