The public federal record on N177DE, 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 US Department of Energy, a government body, certificate issued May 2, 2022, expires May 31, 2029. No fractional interest recorded. [1]

ATTENTIONAirworthiness certificate

No airworthiness certificate is on file. Usual for a newly registered aircraft, a project, or an aircraft that has not flown since a change of registration; ask for the certificate. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 177 for this model in the deregistered file. [2]

CLEARTail number reuse

No other airframe has carried N177DE 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 N177DE. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]

PENDINGTitle chain, liens and 337 forms
