INSULATOR

The 5018174-3 is a genuine Textron Aviation insulator 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. Supplied as a defined part in the manufacturer's catalog, its exact role is set by the aircraft's parts and maintenance data. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies. An unapproved or surplus substitute can introduce fit, material, or paperwork problems that surface at the next inspection; the genuine part avoids that risk. Before installation, match this part number to your aircraft's approved configuration and current effectivity. 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 factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. 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 supports aircraft owners, operators, and MROs worldwide with genuine Cessna and Beechcraft parts from Wichita, Kansas.
