Description
The MS21256-1/2 is a genuine Textron Aviation clip — a fastening or retaining hardware item used in the airframe. It carries an export classification of ECCN 9A991.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated.
Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies. 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.
Part numbers can supersede over time, so verify the current applicable number for your airframe's serial and configuration before installation. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Supplied through Textron Aviation, this part comes from the manufacturer that builds and supports the Cessna and Beechcraft fleets worldwide from Wichita, Kansas.
