What division fabricates and tests hoses, tubes, and sheet metal parts for aircraft structural components?

The division responsible for fabricating and testing hoses, tubes, and sheet metal parts for aircraft structural components is the Airframes division. This division focuses specifically on the structural elements of the aircraft, which includes the body, wings, and other external parts that provide the aircraft with its shape and strength.

Fabrication of hoses and tubes is critical for systems such as fuel, hydraulic, and pneumatic systems, which are essential for the operation and control of the aircraft. Additionally, sheet metal work is vital because these components often require precision engineering to ensure safety and performance standards are met.

In contrast, the other divisions such as Propulsion, Avionics, and Maintenance have different areas of expertise. Propulsion focuses on the engine and thrust systems, Avionics deals with electronic systems and instrumentation, and Maintenance concerns itself with the upkeep and repair of all aircraft systems. Thus, the Airframes division is uniquely suited to handle tasks related to structural components and their fabrication.
