Description
The MS21322-52 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of 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. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Cross-check the part number against your maintenance and parts documentation to confirm fit and current effectivity for your airframe. 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.
Applicability can depend on effectivity blocks and service bulletins; check the IPC and any applicable SBs for your tail number before fitting this part. 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.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Textron Aviation traces its roots to Cessna, founded in Wichita, Kansas in 1927, and Beechcraft, founded there in 1932 — two of general aviation's most storied names, united under one company since 2014.
