Aircraft Wheel and Brake Systems
FSC 1630: Aircraft Wheel and Brake Systems
Federal Supply Class (FSC) 1630 covers aircraft wheel assemblies, brake assemblies, anti-skid units, and associated brake system hardware for military and government aircraft. These safety-of-flight components conform to MIL-SPEC and NAS standards and are stocked at depot and intermediate maintenance levels.
Aircraft wheels and brakes support the aircraft on the ground and bring it to a stop on landing and during rejected takeoffs. Brake performance and heat management are critical to safe operation on runways and carrier decks.
Common items include wheel halves, carbon and steel brake disc stacks, brake assemblies, anti-skid control valves, and tire pressure sensors. Wheels are typically forged aluminum, while brake components use steel and carbon-carbon materials rated for high thermal loads.
