Records check free · 1 to understand · 4 clear

The public federal record on N37281, 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 United Airlines INC, a corporation, certificate issued December 22, 2003, expires January 31, 2029. No fractional interest recorded. [1]

CLEARAirworthiness certificate

Standard certificate for transport, dated December 18, 2003, consistent with the 2003 manufacture year. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 31599 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N37281 was previously assigned to 1 other aircraft: Interstate S-1A (serial 124, cancelled September 15, 1949). 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 N37281. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]

PENDINGTitle chain, liens and 337 forms

These live in the FAA aircraft records file (every document ever filed against the aircraft) and, for larger aircraft, the International Registry. Part of the full report.
