Unsafe Condition
The retaining ring can become unseated from its positional groove on the input shaft of the integrated drive generator (IDG) constant speed drive (CSD), resulting in loss of IDG oil and subsequent disconnection of the IDG, and causing abnormal movement of the input shaft which could damage the engine seal and lead to loss of engine oil and engine shutdown during flight.
