The public federal record on N37BP, 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.
Valid registration to Cilliers Carlo R, an individual, certificate issued January 21, 2026, expires January 31, 2033. No fractional interest recorded. [1]
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]
No earlier tail number is recorded against serial P502 for this model in the deregistered file. [2]
N37BP was previously assigned to 2 other aircraft: Szulewski Paul G H-3 (serial 001, cancelled May 20, 2015); Petersen Bryce Clark PUDDLE JUMPER (serial 1, cancelled March 28, 1991). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]
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]
No NTSB investigation records located under N37BP. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
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.
AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
