Description
The MS21141S0503 is a genuine Textron Aviation fastener — a fastening or retaining hardware item used in the airframe. It carries an export classification of ECCN 9A991.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Part numbers can supersede over time, so verify the current applicable number for your airframe's serial and configuration before installation. 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.
As configurations differ across serials and modifications, validate this part against your aircraft's approved data before purchase. 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.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
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.
