Description
The MS21920-47 is a genuine Textron Aviation clamp — a fastening or retaining hardware item used in the airframe. It carries an export classification of ECCN 9A991.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies.
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. Because interchangeability rules can apply, confirm the exact applicable part for your configuration in the IPC before installation.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
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 company behind this part, Textron Aviation, builds and sustains the Cessna Citation, Beechcraft King Air, Bonanza, and Baron families from its home in Wichita, Kansas.
