## Analysis

AS THE ACFT BEGAN TO ROTATE DURING TAKEOFF ONE PROPELLER BLADE WAS THROWN 1000 FT BEHIND THE ACFT. THE REMAINING BLADE AND HUB BECAME UNBALANCED, TWISTING THE ENGINE AT A 45 DEGREE ANGLE. PLT SHUT DOWN THE ENGINE. ACFT TRAVELED OFF THE LEFT SIDE OF THE RWY AND CARTWHEELED. INSPECTION REVEALED PROPELLER BLADE BROKE APRX 2 INCHES OUTBOARD OF THE HUB. METALLURGICAL TESTS REVEALED NUMEROUS FATIGUE ORIGANS ON BOTH THE BLADE BUTT ENDS AT ITS SEPARATION POINTS AND IN THE PROPELLER ATTACHMENT ON THE FACE OF THE HUB. THE PROPELLER BLADE MOUNTING WHICH ATTACHES TO THE ENGINE HAD BROKEN OUT BETWEEN TWO STUD HOLES. THIS AREA SHOWS FATIGUE AS WELL AS DEFORMATION OF THE MOUNTING SURFACE.
