Description
The MS21921-16D is a genuine Textron Aviation fitting that mounts, locates, or braces a component within the airframe. It carries an export classification of ECCN 9A991.
Because it fixes position within the airframe, a bracket or support must be the correct part to keep alignment true. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Cross-check the part number against your maintenance and parts documentation to confirm fit and current effectivity for your airframe. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Check effectivity and supersession status for your serial number so you order the currently applicable part. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
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.
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.
