Description
The MS21140U0505 is a genuine Textron Aviation fastener — a fastening or retaining hardware item used in the airframe.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection.
Part numbers can supersede over time, so verify the current applicable number for your airframe's serial and configuration before installation. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. 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.
The company behind this part, Textron Aviation, builds and sustains the Cessna Citation, Beechcraft King Air, Bonanza, and Baron families from its home in Wichita, Kansas.
