The public federal record on N6171M, 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 Nikodem James e, an individual, certificate issued September 19, 2017, expires September 30, 2027. No fractional interest recorded. [1]
The airworthiness certificate on file is dated September 7, 2017, 51 years after the 1966 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 691942 for this model in the deregistered file. [2]
N6171M was previously assigned to 1 other aircraft: Maule M-5-235C (serial 7180C, cancelled March 20, 1995). 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]
1 NTSB record under N6171M: Accident on May 2, 1993 at Fowl Cay: serious injuries, substantial damage. Details below. [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.
