Accident Sequence
On the downwind leg of the approach, the pilot selected 10 degrees of flaps. Later, on final approach, the pilot applied full flaps. Approximately 200 yards from the intended touchdown point, the aircraft experienced a rapid rate of descent. In response, the pilot added power to arrest the sink rate. Despite the power application, the aircraft collided with trees on final approach.
Post-Accident Findings
Following the accident, the flaps were observed to be extended 10 degrees. The flap actuator handle was found in the full down position, and the flap circuit breaker was out. A mechanic who inspected the aircraft after the accident reported that no mechanical abnormalities were found.
Equipment Condition
The flap system, including the actuator handle and circuit breaker, was noted to be in a configuration inconsistent with the pilot's account of having selected full flaps. The reason for the discrepancy between the pilot's action and the observed flap position was not determined. The absence of mechanical abnormalities suggests that the flap system was functioning correctly at the time of the inspection.
