Analysis

The captain, who was flying the twin otter from the right seat, entered a right hand traffic pattern for landing. A left quartering, 15 knot headwind, was gusting across the airport. Upon turning to the final approach the captain reduced the aircraft's engine power to the low speed range for the visual approach. As the aircraft neared the runway the rate of descent accelerated. The captain's application of full engine power failed to arrest the aircraft's rate of descent and the aircraft impacted the ground short of the runway.
