Built of
composite
The airframe is composite: carbon fibre or glass fibre set in resin, moulded in large pieces with few joints, which gives smooth shapes but needs different inspection and repair methods from metal. A glass-fibre glider. This is how the Glasflugel H 301 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 N4171, 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 Stewart William S, an individual, certificate issued March 30, 2012, expires March 31, 2028. No fractional interest recorded. [1]

CLEARPrior registrations of this airframe

No earlier tail number is recorded against serial 54 for this model in the deregistered file. [2]

ATTENTIONTail number reuse

N4171 was previously assigned to 4 other aircraft: Mooney M-18C 55 (serial 366, cancelled July 30, 1956); Mooney M-18C 55 (serial 336, cancelled June 14, 1956); Coffman Sam H MONOPLANE (serial I-3122, cancelled April 12, 1929).
