What happened
On the afternoon of June 9, 2002, a Fly Synthesis Storch High Speed Jabiru ultralight, identified by the number 28-XV, was performing a local flight near the Ecrosnes ultralight airfield. While operating within the airfield traffic pattern, the pilot transmitted a radio message stating that they were not feeling well. Witnesses observed the aircraft enter a right-hand turn, during which it appeared to enter a spin before striking the ground. The impact resulted in the destruction of the aircraft and the death of the pilot.
The investigation
The investigation focused on the pilot's health and the flight dynamics leading to the impact. Medical examinations conducted following the accident revealed that the pilot had a history of coronary artery disease. Investigators also reviewed the pilot's flight credentials and medical history, noting that the pilot held a professional helicopter license and had passed an annual medical examination as recently as April 29, 2002. Meteorological conditions at the time of the accident included visibility greater than 10 km, winds from 210 degrees at 10 to 18 knots, and scattered to overcast clouds between 2,600 and 8,000 feet.
Findings
- The primary cause of the accident was a medical emergency involving the pilot.
- The pilot likely suffered a cardiovascular event during the flight, which led to a loss of consciousness or diminished physical and cognitive capabilities.
- This medical episode caused the pilot to lose control of the aircraft, leading to the fatal collision with the ground.
