Description
The MS21245L8 is a genuine Textron Aviation nut — a fastening or retaining hardware item used in the airframe. It is fitted 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 MS21245L8 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Beechcraft Premier aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
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. 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.
Beechcraft was founded in Wichita, Kansas in 1932 by Walter and Olive Ann Beech, and has been part of Textron Aviation since 2014, uniting with Cessna and Hawker. The Beechcraft Premier I was a clean-sheet, composite-fuselage light jet — the first jet Beechcraft designed in-house — supported today through Textron Aviation.
