Water Injection

The system components and parts which inject a water mixture into induction system of turbine andreciprocating engines. Typical parts are pump, switch, tank, valve, etc.

Air Conditioning

The units and systems supplying heated air to the cockpit or cabin. Includes the heat source (heater), controlling aspects, and temperature sensors/indicators. Typical parts are fuel pump, filter, plumbing, circuitry, relay, heat exchanger, igniter, etc.

Airborne Auxiliary Power

The system components which electrically and manually control operation of the APU engine. Typicalparts are relay, control box, etc.

Water Injection

For reports indicating a problem with wiring specific to the Water Injkection System.

Air Conditioning

The units and systems supplying cooled air to the cockpit or cabin. Does not include the temperature control and indicating system. Typical parts are flow valve, relay, condenser, ram air sensor, heat exchanger, cooling turbine, air cycle machine, etc.

Airborne Auxiliary Power

For general reports of APU operation indicating including the temperature indicator, tachometergenerator or indicator (engine speed). Includes the instrument and associated warning system whichsense, transmits, and indicates APU engine speed and temperatures to the flight crew.

Accessory Gearboxes

The units and components which are remotely installed and connected to the engine by a drive shaft andwhich does not include those accessory drives which are bolted to and are immediately adjacent to theengine. The latter item should be filed in JASC code 7200. Does not include accessory drives bolted toand adjacent to engine which are normally filed in JASC code 7260.

Air Conditioning

The units and circuitry other than the control unit which are used for controlling the temperature of the air in the cockpit and cabin. Typical parts are control valves, thermal sensing devices, switches, amplifiers, and wiring.

Airborne Auxiliary Power

The components and parts which collect and direct exhaust gasses from the APU turbine to the aircraftexterior. Includes the movable door fairing. Typical parts are nozzle, door, actuator, seal, clamp, andshield.

Accessory Gearboxes

For reports indicating a problem with wiring specific to the Accessory Gearbox.
