Description
The MS21333-81 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, weighs 0.05 pounds, and measures 3 (L) x 1.75 (W) x 0.7 (H) Inches.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Confirm this part's applicability to your specific aircraft, serial number, and modification status against the approved parts data before you install it. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
Formed in 2014, Textron Aviation unites the Cessna, Beechcraft, and Hawker names and provides genuine factory-parts support across the combined fleet.
