It is registered to an owner whose details are withheld at their request. The FAA lists the registration as "n-number assigned but not yet registered". No airworthiness certificate is on file, which is normal for drones and for aircraft still being built or tested. 1 document is on file: bill of sale (evidence of ownership).

The public federal record on N661KZ, 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.

ATTENTIONRegistration and identity

Registration status is "N-number assigned but not yet registered". An aircraft cannot be operated on an invalid or expired registration; resolve this with the FAA before any transaction. [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 18736P23917 for this model in the deregistered file. [2]

CLEARTail number reuse

No other airframe has carried N661KZ according to the deregistered file. [2]

NOTERecent registry documents

1 document received recently: Bill of sale (evidence of ownership) (October 15, 2026). [3]

CLEARAccident and incident record

No NTSB investigation records located under N661KZ. 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

AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
