Description
The 49145-28A is a genuine Textron Aviation 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 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.
Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration.
Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for.
Textron Aviation traces its roots to Cessna, founded in Wichita, Kansas in 1927, and Beechcraft, founded there in 1932 — two of general aviation's most storied names, united under one company since 2014.
