Analysis
During a formation takeoff, the plt was flying in a left wingman position & the flt entered a relatively steep climb. The plt stated that the airspeed was slightly above the stall speed at about 100 to 150 ft AGL when the left eng lost power & the acft began turning left & losing alt. He reported that the plane stalled & he could not control the left yaw & turn, until after he lowered the nose & regained airspeed. He did not reduce power on the operating eng. Subsequently, the acft struck the ground in a slight nose down attitude. An investigaton revealed that the single spark plug in the left, single cylinder, 2 stroke eng was not firing at the electrode tip.
