The public federal record on N3500X, 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 Helicopter Flight Services LLC, an LLC, certificate issued November 12, 2019, expires November 30, 2029. No fractional interest recorded. [1]
The airworthiness certificate on file is dated August 28, 2019, 19 years after the 2000 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 RN047 for this model in the deregistered file. [2]
N3500X was previously assigned to 1 other aircraft: Mooney M20F (serial 670038, cancelled April 10, 2013). 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 N3500X: Accident on November 19, 1998 at Upland, CA: serious injuries, destroyed. 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.
NTSB records 1
Aircraft on the NTSB record: Mooney M20F · operated under 091
Loss of engine power due to water contaminated fuel and the pilot's inadequate preflight inspection of the airplane. A factor was the failure of the owner/pilot to properly maintain the airplane.
