The airframe is aluminium: sheet metal over a riveted frame, the way most aircraft have been built since the 1940s. This is how the Cessna A185 Skywagon family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.

The public federal record on N18521, 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.

CLEARRegistration and identity

Valid registration to Island Air LLC, an LLC, certificate issued June 20, 2002, expires August 31, 2027. No fractional interest recorded. [1]

ATTENTIONAirworthiness certificate date

The airworthiness certificate on file is dated March 9, 2001, 22 years after the 1979 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]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 185-03812 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N18521 was previously assigned to 3 other aircraft: Beech 58 (serial TH1297, cancelled March 14, 1990); Cessna 150L (serial 15073910, cancelled June 26, 1973); Porterfield CP-40 (serial 501, cancelled May 11, 1948). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]

NOTERecent registry documents

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]

CLEARAccident and incident record

No NTSB investigation records located under N18521. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]

PENDINGTitle chain, liens and 337 forms

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.

PENDINGAirworthiness directives and utilization

AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
