What happened
Witnesses reported observing the pilot make two unsuccessful landing attempts in the dark at the unlit airport. The airplane's landing lights were not on. During a third landing attempt, the airplane collided with power lines and trees. The pilot had a history of heart disease and had been given a special issuance third-class airman medical certificate; however, it was not valid at the time of the accident. A toxicology report indicated the use of Losartan, a prescription medication used to treat high blood pressure. Although the autopsy did not identify evidence of a recent heart attack, the autopsy did identify evidence indicating that the pilot was at risk for a sudden cardiac event that could result in incapacitation and concluded that the pilot died as a result of hypertensive and arteriosclerotic cardiovascular disease. It is likely that the pilot's sudden incapacitation and death during the flight resulted in the accident.
