At approximately 1145 mountain time, a Cessna R172E suffered a damaged wing while taxiing when it was knocked over by jet blast from a DC-9. The student pilot was not injured. The pilot was taxiing to the runway at Albuquerque International Airport when an American Airlines jet was cleared for taxi from Gate B1. As the DC-9 added engine power for taxi, the jet blast struck the Cessna and the wing spar was bent when the wing struck the ground.
