What happened
On October 21, 2000, at approximately 16:30, a Pottier P 180 S amateur-built aircraft, registration F-PYZE, was performing a local flight at Lézignan aerodrome. The pilot, who had constructed the aircraft, had completed five circuit laps and was on final approach for runway 08. Prior to landing, the AFIS controller reported a wind from 120 degrees at 20 knots.
Witnesses observed the aircraft maintaining a stable approach path. However, as the aircraft reached approximately one meter above the ground, the right wing lifted, causing the plane to climb slightly. Observers noted an increase in engine RPM during this maneuver. The aircraft then experienced a sudden roll, inverted, and struck the ground on its left wing, resulting in a total hull loss. The accident resulted in one fatality and one injury to the pilot.
The investigation
The investigation focused on the aircraft's mechanical state and the environmental conditions at the time of the accident. Examination of the wreckage revealed no failures in the flight control systems, and the flaps were found to be fully extended. While the pilot was unable to provide a precise description of the sequence of events, investigators analyzed the meteorological data, which indicated a wind of 120 degrees at 18 knots with gusts reaching 34 knots.
Findings
- The aircraft was operating in weather conditions that were likely a contributing factor, specifically regarding the crosswind component.
- The demonstrated crosswind limit for this aircraft type is 25 knots.
- The primary cause of the accident was the use of the aircraft in marginal conditions.
