What happened
On 10 May 2024, a pilot was conducting a cross-country flight near Auvers-sur-Oise to test a recently purchased Dudek Warp 2 wing. The pilot was accompanied by another paramotor pilot, and the flight was intended for leisure. After an initial rejected takeoff, the pilot successfully departed at 20:22.
While performing a figure-of-eight maneuver, the pilot executed a right-hand turn followed by a left-hand turn. During this sequence, the aircraft began a rapid descent of approximately 140 meters over a period of 50 seconds. Shortly thereafter, the accompanying pilot observed the aircraft entering a steep left-hand turn that quickly transitioned into an accelerating spiral dive. The aircraft struck the ground, resulting in the fatal injury of the pilot and the destruction of the microlight.
The investigation
The BEA examined the wreckage and the wing used in the accident. The Dudek Warp 2 was found to be in nearly new condition, with no damage to the lines, risers, or the wing itself. The engine and electrical components were functional, though significant heat damage was observed in the area of the Li-Po battery, which had undergone thermal runaway following the impact.
The investigation also reviewed the pilot's medical history and the technical characteristics of the wing. The Dudek Warp 2 is a high-performance wing designed for experienced pilots, which can enter an accelerating spiral dive—a high G-force maneuver—if a turn is not correctly controlled.
Findings
- The primary cause of the accident was the wing entering an accelerating spiral dive during a left-hand turn, which the pilot was unable to recover from due to the low altitude.
- The pilot's medical condition, specifically advanced coronary artery disease, may have led to incapacitation under high G-loads.
- The use of beta-blocker medication may have impaired the pilot's ability to react to the sudden acceleration and increased his reaction time.
- The pilot's lack of experience with this specific high-performance wing may have contributed to the inability to exit the maneuver.
