The airframe is aluminium: sheet metal over a riveted frame, the way most aircraft have been built since the 1940s. This is how the Mcdonnell Douglas Helicopter 500 family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.

The public federal record on N520N, 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 Quantumtrace INC, a corporation, certificate issued January 23, 2026, expires January 31, 2033. No fractional interest recorded. [1]

CLEARAirworthiness certificate

Standard certificate for normal, dated July 1, 1992, consistent with the 1992 manufacture year. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial LN031 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N520N was previously assigned to 2 other aircraft: Mcdonnell Douglas Helicopter 500N (serial LN037, cancelled January 7, 1999); Curtiss Robertson ROBIN J-1 (serial 717, cancelled October 18, 1955). 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 N520N. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
