Description
The MS21105-20 is a genuine Textron Aviation clamp — a fastening or retaining hardware item used in the airframe. It carries an export classification of ECCN 9A991.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. Applicability can depend on effectivity blocks and service bulletins; check the IPC and any applicable SBs for your tail number before fitting this part.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Part numbers can supersede over time, so verify the current applicable number for your airframe's serial and configuration before installation.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
As the maker behind the Cessna Citation, Beechcraft King Air, Bonanza, and more, Textron Aviation supports this part through its global factory-parts network from Wichita, Kansas.
