## Discrepancy

(CAN) DURING DISASSEMBLY OF THE ENG AFTER SPLITTING THE HP2 TURBINE DISC FROM THE HPT1 TURBINE DISC IT WAS FOUND THAT LOCKING PLUGS WERE MISSING. THE LOCKING PLUG IS PREVENTING THE LOCKING RING HOLDING THE HP1 TURBINE BLADES TO BE RELEASE. THE LOCKING RING WAS STILL IN POSITION BUT LOCKING PLUG WERE RELEASED BY DAMAGING SURROUNDING AREA OF HP 1 AND HP 2 TURBINE DISC WEBS, BLADES AND NGV. OEM ADVISE.
