## Discrepancy

CLIMBING TO 38000 FT AT CRUISE, PILOT HEARD LOUD NOISE, THINKING IT WAS EMERGENCY PRESSURIZATION VALVE, AIRPLANE THEN YAWED.  PILOT NOTICED POWER DECREASE ON LT ENGINE.  NO WARNING LIGHTS, EMERGENCY INDICATIONS.  PILOT BROUGHT ENGINE TO IDLE. OIL PRESSURE, OIL TEMP, FUEL FLOW, ALL NORMAL. BEGAN DESCENT AND ROUGHLY AT 5000 FT, PILOT HEARD LOUD NOISE FROM LT ENGINE AND SHUTDOWN. THEY MADE A 1 ENGINE LANDING.  PILOT NOTED THAT HE COULD NOT TURN LEFT ENGINE FAN BLADE.
