What happened
The incident occurred shortly after the glider was released from an aerotow. Upon separation, the pilot encountered significant sink conditions which necessitated an immediate return to the departure airport for a precautionary landing. The adverse weather conditions persisted throughout the entire approach phase. Despite efforts to manage the descent, the pilot was unable to flare the aircraft effectively at the last moment. Consequently, the glider impacted the runway with excessive vertical speed, sustaining damage from the hard landing.
The investigation
The investigation focused on the operational circumstances surrounding the precautionary landing. Examination of the event revealed that the primary factor was the inability to execute a proper flare due to the continuous strong sink conditions during the final approach. No mechanical failure of the glider was cited as a cause for the incident.
Findings
The pilot's decision to return to the departure airport was a prudent response to the sudden loss of lift. However, the persistence of the sink allowed no margin for error in the landing technique. The hard landing was a direct result of the meteorological conditions preventing a standard flare maneuver.
