[0002] The integrated drive generator (IDG) of an aircraft is driven by the engine driveshaft, converting mechanical energy into alternating current (AC) energy to provide continuous power to critical components such as the aircraft's avionics systems, lighting equipment, and hydraulic pumps. The integrated drive generator is directly coupled to the engine accessory gearbox, reducing transmission losses and improving reliability.

[0003] When the aircraft is grounded, the integrated drive generator needs to be inspected and maintained. This requires removing the integrated drive generator from the aircraft.
