Description
The MS21920-57 is a genuine Textron Aviation clamp used to fasten, secure, or retain components during assembly of the airframe.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. Confirm this part's applicability to your specific aircraft, serial number, and modification status against the approved parts data before you install it.
Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. Verify the part number and any supersessions against the manufacturer's parts catalog for your model and serial before ordering.
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. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
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 factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide.
This part is cataloged by Textron Aviation, the Wichita, Kansas manufacturer that unites the Cessna, Beechcraft, and Hawker brands.
