Narrative:
THE FLIGHT INSTRUCTOR AND STUDENT PILOT HAD RETURNED TO THE AIRPORT FOR LANDING AFTER CONDUCTING AIRWORK. DURING THE APPROACH THE GLIDER COLLIDED WITH TREES. THE INSTRUCTOR STATED THAT HE ASKED THE STUDENT HOW THE ALTITUDE LOOKED FOR THE APPROACH, AND '...HE [THE STUDENT] RESPONDED THAT WE WERE HIGH AND IMMEDIATELY OPENED THE DIVE BRAKES FULLY AND PUT IN A MODERATE SLIP. I SAID NO....I PUSHED THE DIVE BRAKES SHUT AND TOLD THE STUDENT TO TAKE OUT THE SLIP....I AIMED FOR A NOTCH IN THE TREES, PUT IN [A] CRAB TO STOP THE SIDE DRIFT AND FLY ALONG THE LINE OF THE RUNWAY....BOTH WINGTIPS HIT THE TREES....' ADDITIONALLY, THE INSTRUCTOR REPORTED THAT THERE WERE NO MECHANICAL MALFUNCTIONS OR FAILURES WITH THE GLIDER.

Probable Cause: the flight instructor's inadequate supervision during the final approach which resulted in the student flying a low approach and a subsequent collision with the trees. A factor relating to the accident was the student pilot's failure to maintain a proper glidepath.
