The public federal record on N44HQ, 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 N44Hq Flyingboats LLC, an LLC, certificate issued October 25, 2023, expires October 31, 2030. No fractional interest recorded. [1]
The airworthiness certificate on file is dated March 21, 2025, 74 years after the 1951 manufacture year. A re-issued certificate commonly follows export and re-import, a rebuild, or a return to the register after cancellation. The cause is documented in the FAA aircraft records file, which the full report obtains. [1]
No earlier tail number is recorded against serial 51-025 for this model in the deregistered file. [2]
No other airframe has carried N44HQ according to the deregistered file. [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 N44HQ. 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.
