Accident Sequence
Witnesses observed the airplane making a normal approach for landing when it suddenly rolled to the left, descended, and impacted the terrain approximately half a mile from the runway. Upon arrival at the scene, the airplane was fully engulfed in flames. The flight was conducted in night visual meteorological conditions with the runway lights illuminated. The pilot did not communicate any problems or difficulties while in contact with air traffic control during the flight.
Examination and Radar Data
A postaccident examination of the airframe and engine revealed no anomalies associated with a pre-impact failure or malfunction. Radar track data and weather observations indicated that the pilot had climbed through an overcast cloud layer without the required ATC clearance while en route to the intended destination.
Pilot Information
The pilot previously held a private pilot certificate with single and multi-engine airplane ratings. Subsequently, he was issued a commercial pilot certificate with an instrument airplane rating, based on military flight experience. However, a review of military records and statements from his family indicated that the pilot had never served in the military.
Medical Considerations
The pilot’s medical history and toxicology testing showed he had a history of back pain and was taking medication for that condition, which commonly causes impairment. However, the time proximity of the pilot having taken the medication prior to the accident flight and any possible impairment could not be determined.
Official Findings
The probable cause was determined to be the pilot’s failure to maintain control of the airplane during final approach for landing in night, visual meteorological conditions for undetermined reasons.
