The public federal record on N51AR, 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 Olsem Aerial Application Services LLC, an LLC, certificate issued February 28, 2017, expires February 28, 2030. No fractional interest recorded. [1]
The airworthiness certificate on file is dated June 4, 2008, 38 years after the 1970 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 1523R for this model in the deregistered file. [2]
N51AR was previously assigned to 1 other aircraft: Piper PA-22-150 (serial 227493, cancelled October 16, 1997). 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 N51AR: Accident on July 22, 2010 at Mccook, NE: serious injuries, substantial damage. Accident on July 24, 1994 at Murphy Springs, ID: minor injuries, substantial damage. Details below. [4]
