What happened
On May 30, 2014, at 15:15 local time, a private glider flight was returning from a cross-country mission. As the pilot approached the vicinity of the Montricher airfield (LSTR), the aircraft's altitude was insufficient to reach the designated landing strip. Consequently, the pilot attempted an emergency landing in a nearby field characterized by tall grass. During the landing sequence, the pilot lost control of the LS 8-18, registration HB-3288, resulting in a ground loop.
The investigation
The investigation focused on the circumstances surrounding the landing attempt and the subsequent loss of control. Authorities established that the aircraft was operating under Visual Flight Rules (VFR) for private purposes. The investigation confirmed that the aircraft was unable to maintain the necessary altitude to reach the runway, necessitating the off-field landing. While the aircraft sustained damage to the fuselage, there were no fatalities. One person on board was reported as uninjured or slightly injured.
Findings
- The primary factor in the accident was insufficient altitude to complete the approach to the Montricher airfield.
- The landing surface consisted of tall grass, which contributed to the loss of control during the landing phase.
- The aircraft, an LS 8-18, experienced a ground loop following the touchdown in the field.
