Analysis

The student plt and the CFI agreed that the acft developed a high sink rate as it passed over the departure end of the dirt rwy. The acft collided with the ground about 3/4 mile from the rwys end. The winds were variable but basically from the south at 15-20 KTS. The da was 4500 ft. a ground witnesses thought he heard the eng sputter at the rwys end. The CFI said that because of the lack of climb he checked that the throttle was fully open and then looked back outside. He said that the student did all that he thought could be done so he did not interfere in controlling the acft. No malfunctions were reported by the plts.
