What happened
On 30 September 2019, a pilot operating an Adventure Smart 27L paramotor, registration 64XY, attempted a local flight from a private airfield in Halsou, France. The pilot was flying alongside another paramotor pilot who had already departed. After an initial aborted takeoff attempt, the pilot attempted a second takeoff facing a heading of 330°.
During this second attempt, the aircraft veered sharply to the right toward a line of trees bordering the field. The canopy became entangled in the vegetation, causing the pilot and the harness to be thrown from the aircraft and into the Nive river. The pilot was transported to a hospital, where he later succumbed to injuries resulting from drowning.
The investigation
The BEA examined the wreckage and the circumstances surrounding the takeoff. Investigators found that the engine was transmitting torque at the time of the collision, evidenced by friction marks on the engine housing. The fuel tank remained intact and was approximately 75% full. While the engine and propeller showed some damage, the examination of the canopy and flight controls revealed no mechanical malfunctions or structural failures.
Witnesses observed that the canopy appeared asymmetrical above the pilot during both takeoff attempts. A flight instructor noted that a rigging line may have remained on the upper surface of the right side of the canopy following the first aborted attempt. Such a condition can prevent air from entering the wing tip, creating significant drag and inducing an asymmetric flight path.
Findings
- The primary cause of the accident was canopy asymmetry which led to a loss of control.
- This asymmetry was likely caused by a rigging line being improperly positioned on the upper surface of the wing.
- The aircraft's deviation to the right was further exacerbated by the engine's torque effect when the pilot applied full throttle.
- The pilot may have been under time pressure to catch up with the preceding aircraft, potentially leading to an insufficient canopy inspection during the second takeoff attempt.
