The public federal record on N91MK, 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 Mulaii LLC, an LLC, certificate issued March 5, 2024, expires March 31, 2031. No fractional interest recorded. [1]
The airworthiness certificate on file is dated November 29, 2023, 9 years after the 2014 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 4636647 for this model in the deregistered file. [2]
N91MK was previously assigned to 2 other aircraft: Keeley M/Tidd R MK-1 (serial 001, cancelled January 29, 2018); Cessna 180 (serial 31822, cancelled December 2, 1958). 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]
2 NTSB records under N91MK: Accident on January 24, 2026 at Sioux City, IA: no injuries, substantial damage. Accident on April 24, 2009 at Demopolis, AL: fatal, substantial damage (1 fatal). 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.
