## Discrepancy

WHILE IN FLIGHT, ENGINE LOST POWER WHICH RESULTED IN AUTO ROTATION ENDING IN HARD LANDING.  FOUND THIRD STAGE EITHER STATOR OR 3RD STAGE WHEEL VANE FAILED CAUSING STAGES 4, 5, 6, 7 TO FAIL.  THESE FAILURES FURTHER EXTENDED INTO COMBUSTION CAN AND TURBINE.  ALL 3 MODULES OF ENGINE ARE TO BE SENT TO A MFG SERVICE FACILITY FOR FURTHER DISASSEMBLY.  COMPRESSOR PARTS WILL BE SENT TO FACTORY FOR FURTHER ANALYSIS FOR ROOT CAUSE OF FAILURE.
