Description
The MS21919D4 is a genuine Textron Aviation clamp — a fastening or retaining hardware item used in 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. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Applicability can depend on effectivity blocks and service bulletins; check the IPC and any applicable SBs for your tail number before fitting this part. 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.
Check effectivity and supersession status for your serial number so you order the currently applicable part. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Textron Aviation — parent of the Cessna, Beechcraft, and Hawker lines — supports this part through its genuine factory parts network.
