The public federal record on N4031S, 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 Vertical Concepts INC, a corporation, certificate issued December 9, 2022, expires December 31, 2029. No fractional interest recorded. [1]

NOTEAirworthiness certificate

Standard certificate for balloon; the FAA file gives no certificate date and no manufacture year. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 159 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N4031S was previously assigned to 2 other aircraft: Hiller UH-12E (serial 5171, cancelled June 29, 1981); Sikorsky S-61D (serial 61706, cancelled November 23, 1973). 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 N4031S. 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.

PENDINGAirworthiness directives and utilization
