aluminium
The airframe is aluminium: sheet metal over a riveted frame, the way most aircraft have been built since the 1940s. An all-metal glider. This is how the Let L-13 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 N135BS, 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 Holder Robert W, an individual, certificate issued February 20, 2024, expires February 28, 2031. No fractional interest recorded. [1]

ATTENTIONAirworthiness certificate

No airworthiness certificate is on file. Usual for a newly registered aircraft, a project, or an aircraft that has not flown since a change of registration; ask for the certificate. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 173437 for this model in the deregistered file. [2]

CLEARTail number reuse

No other airframe has carried N135BS according to the deregistered file. [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 N135BS. 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.
