Description
The MS21299-8K is a genuine Textron Aviation washer used to fasten, secure, or retain components during assembly of the airframe. It is applicable to the Premier Model 390. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21299-8K meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Parts like this are shared across the Beechcraft Premier aircraft, reflecting how much structure and hardware these models have in common.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
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.
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.
