Incident Overview
Approximately 30 minutes after refueling, the pilot of a cruising airplane experienced a loss of power in the left engine while at an altitude of 18,000 feet. The pilot was in radio contact with Indianapolis Air Route Traffic Control Center (ARTCC) and immediately advised controllers of the situation, requesting a descent. Air traffic control cleared the flight to 10,000 feet mean sea level (MSL). The pilot's attempts to restart the left engine were unsuccessful. Shortly thereafter, the right engine also lost power.
Pilot and Controller Actions
The controller at Indianapolis ARTCC noted that the airplane was nine miles from the nearest airport. The controller provided the pilot with radar vectors to the airport along with current weather conditions. Despite these efforts, the airplane touched down in a wooded area.
Investigation Findings
Following the accident, the Federal Aviation Administration (FAA) examined the aircraft at the site. Both engines were removed and sent to Pratt & Whitney for detailed examination. The examination of the engines and their accessories disclosed no pre-existing defects. Fuel samples were also taken and tested at Pratt & Whitney's laboratory. The tests revealed evidence of contaminants in the fuel.
Probable Cause
The official probable cause of the incident was determined to be loss of engine power due to fuel contamination.
