Analysis

The acft went through a fence and collided with trees after a 'hand-propped' start. The student plt had exhausted the acft battery power during previous starting attempts. He then tied the acft down at both wings and the tail. He primed the eng with the mixture control full rich, throttle full open and the magnetos off. He then opened the throttle aprx 1/4 inch and turned the magnetos on. The eng started immediately when it was hand-propped and accelerated to a high RPM. The acft broke free of the tie down ropes and collided with and passed through a cyclone fence. The acft came to rest when it collided with two trees on the other side of the fence.
