Description
The MS21141U0503 is a genuine Textron Aviation fastener — 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 9A991.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21141U0503 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.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring.
An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
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.
