Description
The MS21209F6-10L is a genuine Textron Aviation insert heli coil supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It is applicable to the 1900D Airliner. It carries an export classification of ECCN EAR99.
Because the MS21209F6-10L 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.
Because the Beechcraft 1900 aircraft share extensive structure and hardware, a single part like this is often common across several variants.
This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
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. The Beechcraft 1900, a 19-passenger regional airliner derived from the King Air, was produced from 1982 to 2002 and still serves commuter and cargo operators worldwide.
