Description
The MS21919DG1 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of the airframe. It is applicable to the Premier Model 390.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21919DG1 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Because the Beechcraft Premier aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
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. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. The Beechcraft Premier I was a clean-sheet, composite-fuselage light jet — the first jet Beechcraft designed in-house — supported today through Textron Aviation.
