What happened
On May 13, 2002, at approximately 13:50, a Schempp Hirth Ventus CT motorized glider, registration PH-1182, was conducting a local flight after a winch takeoff from the Seyne aerodrome. Following release from the winch, the pilot initially flew toward high ground located to the northwest of the airfield.
GPS data analysis revealed that the pilot's flight path was characterized by several turns as he searched for lift. After finding little initial updraft, the pilot turned toward the Ville-Vieille hill. While crossing an area of updrafts, the pilot turned southeast before turning back toward the northwest. Witnesses on the ground observed the aircraft turn right toward the high ground at an altitude of approximately fifty meters, at which point the glider entered a right-hand spin and struck the ground about one kilometer northwest of the aerodrome. The impact resulted in the death of the pilot and the total destruction of the aircraft.
The investigation
The investigation examined the flight path via onboard GPS data and reviewed the pilot's recent flight history and experience. The pilot, aged 49, held a Dutch license and had accumulated 1,150 total flying hours, including 75 hours on this specific type. While the pilot had performed a check flight with an instructor two days prior to the accident, he had not flown in the Alps since 2000. Investigators also reviewed meteorological conditions at the site, which were noted as CAVOK with a 10-knot wind.
Findings
- The primary cause of the accident was the inadequate control of flight parameters while maneuvering through areas of updrafts.
- A contributing factor was the pilot's decision to continue the flight and fly away from the aerodrome in an attempt to locate more favorable soaring conditions.
