Records check free · 2 to understand · 3 clear

The public federal record on N1637D, 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.

CLEARRegistration and identity

Valid registration to Thigpen Don L II, an individual, certificate issued September 21, 2023, expires September 30, 2030. No fractional interest recorded. [1]

ATTENTIONAirworthiness certificate date

The airworthiness certificate on file is dated June 26, 2015, 63 years after the 1952 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]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 18-1637 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N1637D was previously assigned to 1 other aircraft: Cessna 170B (serial 20279, cancelled July 25, 1974). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]

NOTERecent registry documents

No bills of sale, loans or releases have reached the registry in recent weeks. The index covers only recent filings; older liens are in the records file. [3]

CLEARAccident and incident record

No NTSB investigation records located under N1637D. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
