## Discrepancy

(CAN) BEFORE ACHIEVING TAKE-OFF POWER, THE ENGINE EMITTED A LOUD NOISE ACCOMPANIED BY A LOW OIL PRESSURE WARNING ANNUNCIATION.  THE CREW ABORTED TAKE-OFF AND SHUT THE ENGINE DOWN.  SUBSEQUENT INSPECTION REVEALED SEIZURE OF THE LOW PRESSURE ROTOR.  MFG WILL MONITOR THE INVESTIGATION OF THIS EVENT AND WILL ADVISE OF ROOT CAUSE, ONCE ESTABLISHED.
