CLAMP

The MS21122WC4 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of the airframe. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Check effectivity and supersession status for your serial number so you order the currently applicable part. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. This part is backed by Textron Aviation's global parts and service network, which sustains one of the largest active fleets in general and business aviation.
