Description
The MS21914-8K is a genuine Textron Aviation cap supplied for use on the aircraft, with its precise function defined by the aircraft's parts data.
As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. Cross-check the part number against your maintenance and parts documentation to confirm fit and current effectivity for your airframe.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Before installation, match this part number to your aircraft's approved configuration and current effectivity.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated.
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.
Textron Aviation traces its roots to Cessna, founded in Wichita, Kansas in 1927, and Beechcraft, founded there in 1932 — two of general aviation's most storied names, united under one company since 2014.
