## Discrepancy

(CAN) PILOT REPORTED A LOUD BANG AND TORQUE DROPPING OFF ON LANDING.  THE SUBJECT ENGINE WAS REMOVED FROM SERVICE AND SENT FOR INVESTIGATION AND REPAIR.  INVESTIGATION RESULTED IN THE FINDING OF ONE MISSING FIRST STAGE STATOR VANE (I.E. 1 OF 44) FROM THE 1ST STAGE STATOR VANE ASSY. THE FRACTURED STATOR VANE CAUSED DOWNSTREAM COMPRESSOR DAMAGE, WHICH FURTHER RESULTED IN THE COMPRESSOR STALLING (I.E. LOUD BANG) AND THE ENGINE TO LOSE POWER (I.E. TORQUE DROPPING OFF).
