What happened
On 25 February 2022, a Jodel D195 microlight, registration W42SF, departed from Roanne-Renaison aerodrome for a cross-country flight to Blois-Le Brelam. Shortly after takeoff from runway 02, the pilot broadcast a message over the radio indicating a problem and an intention to land again.
During the initial climb, the pilot executed a left turn to return to the airfield. Witnesses observed the aircraft's climb appeared normal initially, but noted a change in attitude and instability on the roll axis at approximately 300 feet. As the aircraft approached the aerodrome perimeter to intercept the runway centerline, the left wing stalled at a very low altitude, approximately 20 meters. The aircraft subsequently struck the ground near the aerodrome's western boundary fence, resulting in the fatal injury of the pilot and the destruction of the aircraft.
The investigation
The BEA examined the wreckage and flight control systems, finding the linkages to be continuous and no mechanical anomalies in the controls. The propeller was rotating at the time of impact. Investigators also reviewed the pilot's training history, noting his experience as a glider pilot and his recent microlight training. Meteorological data indicated a temperature of 5°C with 69% humidity, conditions that presented a risk of carburettor icing. The investigation also considered the pilot's decision-making regarding the flight path during the power reduction event.
Findings
- The pilot likely experienced a partial or total reduction in engine power during the initial climb, which may have been caused by carburettor icing during the ground phase.
- The pilot attempted a turn-around to return to the runway rather than continuing straight ahead on the runway centerline, an area where the environment was suitable for a forced landing.
- The stall was triggered during the turn-around, potentially exacerbated by an inappropriate nose-up input while attempting to clear the aerodrome boundary fence.
- The pilot's decision to turn may have been influenced by a desire to minimize aircraft damage or by drawing parallels to glider emergency procedures.
