Description
The S1771-3 is a genuine Textron Aviation knob that operates a door, panel, or access point. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN 9A991, weighs 0.02 pounds, and measures 1.4 (L) x 0.95 (W) x 0.45 (H) Inches.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the S1771-3 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Parts like this are shared across the Cessna Skyhawk and Skylane aircraft, reflecting how much structure and hardware these models have in common.
As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
Built by Textron Aviation, whose Cessna line was founded in Wichita, Kansas in 1927 and joined Textron in 1992, this part carries one of general aviation's most storied names. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
