STUD

The 401977P003 is a genuine Textron Aviation stud — a fastening or retaining hardware item used in the airframe. It carries an export classification of ECCN 9A991. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Applicability should always be confirmed against the aircraft's IPC and effectivity records prior to fitting the part. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Applicability can depend on effectivity blocks and service bulletins; check the IPC and any applicable SBs for your tail number before fitting this part. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. 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 — parent of the Cessna, Beechcraft, and Hawker lines — supports this part through its genuine factory parts network.
