Description
The MM20-1057 is a genuine Textron Aviation seat lock supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN 9A991, weighs 1.47 pounds, and measures 1.4 (L) x 16.65 (W) x 1.45 (H) Inches.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MM20-1057 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
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. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
