Incident Overview
On September 6, 2000, at approximately 09:00 local time, a Lockheed C-130A Hercules registered as N116TG was destroyed in a collision with terrain near Burzet, in the Ardèche department of France. The aircraft was operating out of the Marignane Civil Security Base for a forest fire suppression mission. The accident resulted in the deaths of the copilot and the flight engineer, while the captain and the cargo mechanic sustained injuries.
Operational Context and Sequence of Events
The crew had departed from Aubenas airfield to perform a retardant drop on the southern edge of a forest fire. This was their second approach of the morning. The Rescue Operations Commander (COS) assigned the mission via radio, instructing the crew to follow a 140-degree heading. Witnesses and the COS observed the aircraft making a sudden left turn followed by a steep descent toward the valley leading to Burzet. Residents reported seeing the plane bank sharply at low altitude over the town before climbing slightly toward the fire zone.
The COS noted that the aircraft passed under the fire's edge without releasing its load and subsequently struck a wooded ridge. A plume of smoke was observed immediately after the aircraft disappeared from view. The wreckage was found disintegrated on a mid-slope. Examination of the debris revealed no mechanical failures; the retardant drop doors were closed, and the aircraft was within manufacturer-defined weight and balance limits.
Environmental and Human Factors
Weather conditions at the time included a wind from 340 degrees at 10–15 knots, clear skies (CAVOK), a temperature of 20°C, and a QNH of 1020 hPa. The captain reported being dazzled by the sun and hindered by smoke during the final approach. A reconstruction flight conducted the following day in similar lighting conditions confirmed that solar glare between Burzet and the target zone likely impaired the crew's vision. Additionally, shadows cast by eastern terrain may have distorted distance perception.
Crew Experience and Contributing Factors
The captain, a 53-year-old American with 5,500 total flight hours (4,000 on the C-130), had extensive fire-fighting experience. The copilot, a 33-year-old French national with 2,500 total hours and only 270 on the C-130, lacked specific type rating but was selected for the flight controls due to his superior ability to communicate in French with ground control. Flight tests indicated the crew operated the aircraft at the limits of its performance envelope during the final approach, likely entering a second regime of flight (stall conditions) which prevented them from gaining sufficient altitude to clear the terrain. The high workload on the copilot, combined with visual distractions and potential complacency due to it being their last mission of the season, contributed to the inability to execute an emergency drop or recover from the low-altitude maneuver.
