Description
The MS21103D4 is a genuine Textron Aviation clamp plain support loop — a support fitting that secures or positions a component in the airframe. It is applicable to the Beechjet 400/400A, Citation III, VI or VII, and Stationair. It carries an export classification of ECCN EAR99.
Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21103D4 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records.
Because the Beechcraft, Cessna Citation, and Cessna Stationair 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. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. 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.
Both the Cessna and Beechcraft lines are supported today by Textron Aviation, formed in 2014 to unite the two historic Wichita manufacturers with Hawker. The Beechjet 400, which began life as the Mitsubishi Diamond and later became the Hawker 400, is a light business jet supported today through Textron Aviation.
