Analysis

The pilot allowed the aircraft to become too close to terrain while soaring. A steep turn to reverse direction resulted in entry into an accelerated stall at low altitude. The pilot lowered the nose of the aircraft to recover, however, while lowering the nose of the aircraft tree tops were struck in flight. Although the left aileron, horizontal stabilizer and elevator were damaged, the pilot was able to return to the departure airport and land.
