Accident Sequence
On final approach, the aircraft began sinking rapidly. The pilot applied power, but the left engine did not respond, causing a sharp left roll. Reducing power regained control, but the aircraft struck the tops of trees located 1,500 feet from and level with the approach end of the runway. The pilot managed a slight climb but, anticipating a hard runway impact, added power again. The aircraft rolled left, veered off the runway, and collided with more trees.
Pilot Statements
In a verbal report to FAA inspectors, the pilot described the engine unresponsiveness on final. In a written statement, she reported encountering a sudden downdraft after clearing a group of tall pine trees surrounding the runway. She stated that full rich mixture settings were used during the approach.
Investigation Findings
Surface winds were light and variable. Computed density altitude was 10,000 feet. FAA inspectors examined the spark plugs, which were heavily sooted. An FAA airworthiness inspector found no mechanical discrepancies with the engines.
