Description
The 4589041-4QCP310 is a genuine Textron Aviation cupholder 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.
This is a cataloged factory part whose form, fit, and function are established by the manufacturer's approved data. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
Before installation, match this part number to your aircraft's approved configuration and current effectivity. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application.
Applicability should always be confirmed against the aircraft's IPC and effectivity records prior to fitting the part. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance.
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. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require.
Textron Aviation is one of the world's largest general-aviation manufacturers, backing the Cessna, Beechcraft, and Hawker fleets with genuine factory parts.
