Description
The MS21241-12C008 is a genuine Textron Aviation bearing that supports rotational or pivoting motion within a mechanism. It fits the 1900 Airliner and 1900C Airliner.
Because the MS21241-12C008 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Parts like this are shared across the Beechcraft 1900 aircraft, reflecting how much structure and hardware these models have in common.
A bearing or bushing sets how a shaft or pivot moves and wears; the right part keeps that motion as designed. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
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. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Beechcraft was founded in Wichita, Kansas in 1932 by Walter and Olive Ann Beech, and has been part of Textron Aviation since 2014, uniting with Cessna and Hawker. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
