Description
The MS21141U0603 is a genuine Textron Aviation fastener used to fasten, secure, or retain components during assembly of the airframe. It carries an export classification of ECCN EAR99, weighs 0.02 pounds, and measures 1.6 (L) x 0.3 (W) x 0.4 (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. Before installation, match this part number to your aircraft's approved configuration and current effectivity.
Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
This part is cataloged by Textron Aviation, the Wichita, Kansas manufacturer that unites the Cessna, Beechcraft, and Hawker brands.
