An aircraft accessory drive system 100 comprising: a drive shaft 102 providing a drive input; a critical accessory 106 (for example a fuel pump, oil pump or flight surface actuator) directly coupled to the drive shaft and directly driven by the drive shaft; a parasitic drive system 110 transmitting drive input from the drive shaft to a less critical accessory 108 (for example a fuel pump or a refrigerant pump). The parasitic drive system comprises a torque limiter 112 which decouples the parasitic drive system from the drive shaft and the critical accessory in response to a jam affecting the parasitic drive system or one or more of the less critical accessories. Also disclosed is a gas turbine engine comprising an aircraft accessory drive system, and an aircraft comprising an aircraft accessory drive system.
