SEAL

The 49145-27A is a genuine Textron Aviation seal used to keep a joint or pass-through tight. It carries an export classification of ECCN 9A991. A seal or gasket keeps a joint tight against its service conditions; only the specified part reliably maintains that integrity. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Part numbers can supersede over time, so verify the current applicable number for your airframe's serial and configuration before installation. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. Cross-check the part number against your maintenance and parts documentation to confirm fit and current effectivity for your airframe. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. 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. Supplied through Textron Aviation, this part comes from the manufacturer that builds and supports the Cessna and Beechcraft fleets worldwide from Wichita, Kansas.
