Analysis

A takeoff was initiated from a 3539 ft wet/upsloping rwy. The gross wt of the acft was about 9300 lbs (300 lbs under themax gross wt). The plt stated the acft accelerated, but never reach '107.' After using about 2700 ft, the plt decided to abort the takeoff, he put both props in reverse & applied full brakes. The acft continued off the departure end of the rwy, went thru the perimeter fence, crossed a 4 lane road & median, hit a utility pole & finally impacted a large tree about 850 ft from the end of the rwy. The plt used a 5 deg flap setting. The performance manual showed that a take-off distance to cross over a 50 ft obstruction was 1900 ft. the manual stated that for either 5 or 20 deg of flaps, allow the acft to accelerate to 70 to 80 KTS, before applying back pressure on the elevator control, then the acft should lift off at about 93 to 96 KTS. An investigation disclosed no power plant or control malfunction.
