Description
The MS21919WD4 is a genuine Textron Aviation clamp — a fastening or retaining hardware item used in the airframe. It is applicable to the King Air B200, B200T, B200C or B200CT. It carries an export classification of ECCN EAR99.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21919WD4 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 King Air aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated.
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 King Air first flew in 1964 and became the best-selling business turboprop in history — still built today as the King Air 260 and 360.
