The public federal record on N51794, 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 Christiansen Aviation LLC, an LLC, certificate issued August 24, 2022, expires August 31, 2029. No fractional interest recorded. [1]

NOTEAirworthiness certificate

Standard certificate for normal; utility; 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 17274348 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N51794 was previously assigned to 1 other aircraft: Fairchild M-62A (serial T43-5484, cancelled May 13, 1948). 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 N51794. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]

PENDINGTitle chain, liens and 337 forms
