The public federal record on N3739K, 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 Sobota Mark S, an individual, certificate issued November 28, 2018, expires November 30, 2028. No fractional interest recorded. [1]
The airworthiness certificate on file is dated August 26, 2007, 9 years after the 1998 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 117609987W979 for this model in the deregistered file. [2]
N3739K was previously assigned to 2 other aircraft: Piper PA-28-140 (serial 28-23716, cancelled October 31, 1978); Globe GC-1B (serial 1432, cancelled June 16, 1949). 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 N3739K. 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.
