## Analysis

WHILE CLIMBING THROUGH ABOUT 6500 FT, A LOUD BANG WAS HEARD AND THE PILOT SAW THE ENGINE COWLING BUCKLE. ABOUT 10 SECONDS LATER, THE ENGINE CEASED TO OPERATE. THE PILOT DECLARED AN EMERGENCY AND LANDED ON AN UNCONTROLLED AIRPORT. AFTER LANDING, AN EXAMINATION OF THE AIRCRAFT REVEALED THAT THE PROPELLER HAD SEPARATED AND THERE WAS SUBSTANTIAL DAMAGE FROM OBVIOUS ENGINE VIBRATION. THE PROPELLER ASSEMBLY WAS FOUND ON A HIGHWAY WITH ONE BLADE MISSING. A METALLURGICAL EXAMINATION REVEALED THAT THE BLADE HAD SEPARATED AFTER THE PROPELLER HUB, MCCAULEY PN TCP3EA-PC3, HAD FAILED FROM FATIGUE.
