What happened
The pilot reported that while on final approach for landing, the aircraft experienced a rapid and unexpected loss of altitude. During this descent, the landing gear made contact with a power line, causing the wire to break. Despite the impact, the glider continued its trajectory and eventually descended onto a nearby road.
The investigation
A thorough examination of the accident site and the aircraft was conducted to determine the cause of the incident. Investigators found no evidence of any pre-impact mechanical malfunction or failure within the aircraft systems that could account for the altitude loss.
Findings
The pilot later provided a written statement questioning whether the spoilers had been fully retracted before landing. This uncertainty suggests that inadvertent spoiler deployment may have contributed to the excessive sink rate and subsequent altitude loss during the final phase of flight.
