Description
The 0550364-9 is a genuine Textron Aviation hinge assembly used to hinge, latch, or operate a door, panel, or access point. It fits the Skyhawk and Skylane. It carries an export classification of ECCN 9A991.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the 0550364-9 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Because the Cessna Skyhawk and Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Parts in a mechanical or control run must match the design geometry to keep rigging, travel, and feel correct. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front.
For a regulated aircraft component, correct identification by factory part number is what guarantees the exact form, fit, and function the design calls for. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. With over 44,000 built, the Cessna Skyhawk is the best-selling aircraft ever made and is still produced today.
