Analysis

The acft was landed in a pasture about 2 miles from the arpt after the acft began to descen 'behind the power curve' after takeoff. The plt said he used full power for takeoff but the takeoff was longer than normal. The da was computed to be 9286 ft. after takeoff the plt said he raised the lndg gear but a witness disagreed. The flt then reduced pwr and as RPM was reduced, noted that the mp was only 24 in. The acft began a descent which the plt said could not be stopped with power so he landed gear down in a pasture. The acft collided with 2 ditches and a fence during the 1500 ft roll. The engs were found to operate normally after the accident.
