A glider pilot avoided a stall by deliberately striking a power line pole with the right wing, severing part of the wing and landing in a swamp.

Event Summary

A pilot reported that while entering the traffic pattern for runway 30 at approximately 900 feet, they completed a right turn to base. Realizing the aircraft was too high, the pilot deployed the spoilers halfway. During the turn to final, the pilot noticed they were too low and observed the airspeed dropping to the stall point. To avoid a stall, the pilot lowered the aircraft's nose and realized they would not reach the airport.

Maneuver and Impact

The pilot then flew under power lines and deliberately struck a power line pole with the right wing at approximately 30 feet above ground level to dissipate energy. About 10 feet of the outboard right wing was severed from the aircraft. The aircraft rotated 90 degrees to the right and dropped approximately 15 feet before coming to rest in a swamp about 200 yards from the airport.

Witness Observation

A witness stated that they clearly observed the glider's spoilers in a fully deployed position when the aircraft rolled out on final.
