The 4631-81 is a genuine Textron Aviation bracket toilet assembly that mounts, locates, or braces a component within the airframe. It carries an export classification of ECCN 9A991.
Mounting and support hardware locates equipment, lines, or structure at defined points, and the exact part keeps everything positioned as designed. Confirm this part's applicability to your specific aircraft, serial number, and modification status against the approved parts data before you install it.
On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
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.
Formed in 2014, Textron Aviation unites the Cessna, Beechcraft, and Hawker names and provides genuine factory-parts support across the combined fleet.
