The public federal record on N63K, 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 Yellowstone Aviation INC, a corporation, certificate issued February 10, 1996, expires July 31, 2029. No fractional interest recorded. [1]

NOTEAirworthiness certificate

Standard certificate; the FAA file gives no certificate date. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 305 for this model in the deregistered file. [2]

CLEARTail number reuse

No other airframe has carried N63K according to the deregistered file. [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 N63K. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
