The public federal record on N638, 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 Aero Mobil INC, a corporation, certificate issued May 16, 2012, expires May 31, 2028. No fractional interest recorded. [1]
The airworthiness certificate on file is dated April 28, 1981, 43 years after the 1938 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 638 for this model in the deregistered file. [2]
N638 was previously assigned to 3 other aircraft: Sikorsky HSS-1 (serial SS581144, cancelled August 10, 1960); Lincoln Aircraft Co STANDARD 5 (serial 103, cancelled May 16, 1938); Lincoln Standard Aircraft Co BIPLANE (serial 47350, cancelled September 8, 1928). 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 N638: Accident on September 14, 1984 at Hollister, CA: 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.
