The public federal record on N331TB, 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 Massachusetts Institute of Technology, a corporation, certificate issued August 18, 2025, expires August 31, 2032. No fractional interest recorded. [1]
The airworthiness certificate on file is dated September 5, 2025, 33 years after the 1992 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 340B-331 for this model in the deregistered file. [2]
N331TB was previously assigned to 1 other aircraft: Underland G/Finstrom D BROKAW BULLET (serial 2GTP, cancelled May 19, 2015). 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 N331TB: Accident on July 29, 1999 at Oshkosh, WI: no 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.
