Description
The MS21919BH25 is a genuine Textron Aviation clamp — a fastening or retaining hardware item used in the airframe. It carries an export classification of ECCN EAR99.
Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. As configurations differ across serials and modifications, validate this part against your aircraft's approved data before purchase.
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. Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk.
Textron Aviation supports aircraft owners, operators, and MROs worldwide with genuine Cessna and Beechcraft parts from Wichita, Kansas.
