Description
The MS21141S0506 is a genuine Textron Aviation blind fastener used to fasten, secure, or retain components during assembly of the airframe. It carries an export classification of ECCN EAR99.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. 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Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Verify the part number and any supersessions against the manufacturer's parts catalog for your model and serial before ordering. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
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.
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.
