DURING THE TAKEOFF ROLL, A PROPELLER BLADE TIP FAILURE OCCURRED ON THE LEFT ENGINE. ABOUT 9 INCHES OF THE BLADE TIP SEPARATED AND ENTERED THE TOP SIDE OF THE FUSELAGE ABOUT 1 FT BEHIND THE PILOT'S HEAD. THE BLADE TIP SEVERED THE THROTTLE, FUEL MIXTURE, CARBURETOR HEAT AND PROPELLER CONTROL CABLES TO THE LEFT ENGINE. ALSO, THE AILERON CABLE BECAME JAMMED IN THE FULL LEFT POSITION AND THE RIGHT ENGINE CABLES WERE DAMAGED. REPORTEDLY, THE LEFT ENGINE WENT TO IDLE POWER AND THE PILOT HAD TO SWITCH THE MAGNETOS OFF IN ORDER TO ABORT THE TAKEOFF.
