What was found
(CAN) LOCATING PIN BACKED OUT CAUSING DAMAGE TO GEAR TRAIN RESULTING IN AN UNSCHEDULED ENGINE REMOVAL. THIS PIN RETAINS THE STUD FOR THE IDLER ASSEMBLY AND IT WAS FOUND TO BE NOT STAKED INTO THE DIAPHRAGM CASE PROPERLY. THIS CAUSED THE PIN TO EVENTUALLY VIBRATE OUT AND JAM INTO THE RGB GEARS.
