Aircraft Accident/Incident Report
Worcester, Vermont 05682
Saturday, August 14, 1999 13:08 EDT
NTSB Narrative Summary Released at Completion of Accident
The pilot received three weather briefings from a flight service station prior to departure. The briefings included forecasts of thunderstorm activity along the planned route of flight, and in the area of the departure airport. The pilot was asked by the weather briefer if the airplane was equipped with weather radar. The pilot stated that he had a stormscope and weather radar. He departed the runway with a 15-20 knot tailwind, did not follow the published instrument departure procedure, and flew south toward mountainous terrain. The wreckage was located about 200 feet from the summit, on the south side of the mountain. Witnesses at the airport and in the vicinity of the accident site report hearing thunder about the time of the accident. Additionally, weather imageries and surface observations confirmed areas of heavy precipitation south of the airport, in the vicinity of the accident site, at the time of the accident. The pilot made four brief transmissions to Air Traffic Control, but was never in radar contact.
NTSB Probable Cause Narrative
The pilot's inadequate in-flight planning/decision, his failure to follow the published instrument departure procedure for the particular runway, and his continued flight into known adverse weather. A factor was thunderstorms.
