Analysis

The acft were to perform & the two plts agreed to a staggered takeoff with the 2nd plt counting to 5 prior to commencinghis takeoff. They positioned themselves abreast of each other on the rwy. The plt of N65P commenced her takeoff from the right side of the 75 ft wide rwy. Upon reaching full throttle, she experienced a momentary loss of power. She retarded her throttle & the eng began to operate properly. As she was about to reapply full power, her acft was struck by N80053. The plt of N80053 had counted to 5 after N65P began its takeoff roll. After about 50 ft of the takeoffground run, in a 3-point attitude, N80053 collided with N65P. The collision was on the left side of the rwy. There is no forward visibility in a pitts S2A when the tail wheel is on the ground.
