Description
The MS21914-5 is a genuine Textron Aviation cap pressure seal that seals a joint or opening against air, fluid, or contamination. It carries an export classification of ECCN 9A991.
Material and dimensions make a seal work; the correct factory part is what keeps the joint from leaking in service. 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. Because aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean.
Cross-check the part number against your maintenance and parts documentation to confirm fit and current effectivity for your airframe. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Formed in 2014, Textron Aviation unites the Cessna, Beechcraft, and Hawker names and provides genuine factory-parts support across the combined fleet.
