Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot said that he was on a short final approach to land. The airspeed was between 70 and 75 knots indicated, and one-third flaps were extended. When he felt he was in a position to land, he retarded the throttle to idle. The airplane settled rapidly, and the pilot reapplied power. The airplane struck trees in a ravine 300 feet short of the runway. Both wings and the fuselage were buckled. The pilot said that if he had come in higher and faster, the accident most likely would not have occurred.
