## Analysis

DURING AN INSTRUCTIONAL FLIGHT, AFTER TAKEOFF, AT 300 FEET, THE PILOT AND STUDENT SAID THEY HEARD A LOUD BANG. THE ENGINE EXPERIENCED A LOSS OF POWER AND THE PILOT NOTED THAT THE TOP OF THE ENGINE COWLING WAS GONE. A FORCED LANDING WAS MADE OFF THE RUNWAY. DURING THE LANDING ROLL THE AIRCRAFT COLLIDED WITH A FENCE. INVESTIGATION REVEALED THAT ONE PROPELLER BLADE SEPARATED FROM THE HUB IN FLIGHT. INSPECTION OF THE PROPELLER BLADE INDICATED SEVERE FATIGUE CRACKING.
