The NTSB's narrative final · quoted from the NTSB record
THE PLT TOOK OFF SO EARLY IT WAS DESCRIBED BY A WITNESS AS STILL BEING DARK. THE ELEVATION OF THE ACCIDENT WAS HIGHER THAN THE TAKEOFF POINT. THE OPERATOR SAID THE PLT TENDED TO BE EASY ON THE EQUIPMENT AND THROTTLED BACK SHORTLY AFTER TAKEOFF. HE STATED THAT THE ENGINE SOUNDED NORMAL UNTIL IMPACT WITH THE TREES. THERE WAS NO WIND. IN THE OPINION OF THE OPERATOR THE PLT GOT BEHIND THE POWER CURVE BEFORE HE REALIZED IT. THE PLT DUMPED THE LOAD AT SOME POINT IN THIS OCCURRENCE.
