Description
The 8189 is a genuine Textron Aviation gasket 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. 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.
Confirm fitment against your airframe's parts data — effectivity, modifications, and supersessions all affect which number applies. 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. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
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.
Textron Aviation supports aircraft owners, operators, and MROs worldwide with genuine Cessna and Beechcraft parts from Wichita, Kansas.
