Description
The MS21914-2 is a genuine Textron Aviation cap supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It carries an export classification of ECCN EAR99.
Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. Confirm this part's applicability to your specific aircraft, serial number, and modification status against the approved parts data before you install it.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. 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.
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.
