Description
The MS21043-6 is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It is applicable to the Bonanza 36, Bonanza F33, G33, F33A or F33C, Citation CJ1 or CJ1+, Citation CJ2 or CJ2+, Citation CJ3, CJ3+, CJ3+ Gen 2, CJ3 Gen 3, Citation Excel, XLS, XLS+, XLS Gen 2, Citation III, VI or VII, Citation Longitude, Citation M2, M2 Gen 2, M2 Gen 3, and Citation Sovereign or Sovereign+, among other compatible variants. It carries an export classification of ECCN EAR99, weighs 0.01 pounds, and measures 0.55 (L) x 0.55 (W) x 0.35 (H) Inches.
Because the MS21043-6 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer.
Because the Beechcraft Bonanza, Cessna Citation, Cessna Skyhawk, and 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.
These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. First delivered in 1947, the Bonanza earned a lasting reputation for build quality and honest handling over one of the longest production runs in aviation history.
