THE EXCEEDING OF THE AIRPLANE'S TAKEOFF PERFORMANCE CAPABILITY BY THE PILOT'S INADEQUATE PREFLIGHT PREPARATION..

Read the full NTSB narrative

ACCORDING TO THE PILOT AND WITNESSES, THE AIRPLANE FAILED TO ESTABLISH AN ADEQUATE CLIMB FOLLOWING INITIAL LIFTOFF. IT CLEARED 20 FOOT TREES AT THE END OF THE RUNWAY, BUT DID NOT CLEAR A 30 FOOT POWER POLE CROSS BAR AND WIRES. THE TAKEOFF WAS ATTEMPTED IN CALM WINDS FROM A 1,500 FOOT SOD STRIP THAT HAD AN UPHILL SLOPE. PERFORMANCE DATA INDICATED THAT FOR THE CONDITIONS THAT EXISTED AT THE TIME, THE AIRPLANE REQUIRED AN 875 FOOT GROUND RUN AND 1,775 FEET TO CLEAR A 50 FOOT OBSTACLE. THE AIRPLANE STRUCK THE POWER POLE 1800 FEET FROM THE DEPARTURE END OF THE RUNWAY. THE PERFORMANCE DATA DID NOT TAKE INTO ACCOUNT THE SOD RUNWAY OR THE UPSLOPE. THE PILOT SAID IN HIS REPORT THAT GIVEN THE OPPORTUNITY TO DO IT AGAIN, HE WOULD NOT HAVE ATTEMPTED THE TAKEOFF UNDER THE SAME CONDITIONS.
