RING

The 636144P005 is a genuine Textron Aviation ring supplied for use on the aircraft, with its precise function defined by the aircraft's parts data. It carries an export classification of ECCN 9A991. As a factory-supplied item for a type-certificated aircraft, this part is defined by the manufacturer's specification and applicability data. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Applicability should always be confirmed against the aircraft's IPC and effectivity records prior to fitting the part. 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. Applicability can depend on effectivity blocks and service bulletins; check the IPC and any applicable SBs for your tail number before fitting this part. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Textron Aviation — parent of the Cessna, Beechcraft, and Hawker lines — supports this part through its genuine factory parts network. Request pricing and availability for 636144P005 on Flying411.
