Description
The 44-221 is a genuine Textron Aviation ring used to keep a joint or pass-through tight. It carries an export classification of ECCN 9A991.
Material and dimensions make a seal work; the correct factory part is what keeps the joint from leaking in service. Because interchangeability rules can apply, confirm the exact applicable part for your configuration in the IPC before installation.
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. Because a single part number can be superseded or vary by effectivity, confirm applicability against your aircraft's Illustrated Parts Catalog (IPC) and serial-number effectivity before ordering.
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. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated.
Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
Textron Aviation — parent of the Cessna, Beechcraft, and Hawker lines — supports this part through its genuine factory parts network.
