According to the pilot in the low-wing airplane, he was cleared by ground control to taxi to runway 22R via "Alpha and November." Taxiway Alpha runs parallel to runway 22R. The pilot approached taxiway Alpha via taxiway Mike, and before entering the intersection of taxiways Alpha and Mike, he "looked in all directions for aircraft" and then proceeded to turn left onto taxiway Alpha without stopping. His airplane's right wing collided with the left side of another airplane already taxiing via Alpha to 22R. He asserted that the other airplane was moving very fast when the collision occurred. His airplane sustained substantial damage to the right aileron. According to the student pilot in the high-wing airplane, he received clearance from ground control to taxi to runway 22R via "Alpha and November." He recalled that he was established on Alpha and heading toward 22R with his landing lights on. He saw the low-wing airplane approaching the intersection of taxiway Alpha and Mike from the nonmovement area. He reported that the low-wing airplane turned left onto taxiway Alpha without stopping. The low-wing airplane's right wing collided with the left side of his airplane. His airplane sustained damage to the left-wing lift strut, the left-wing support struts, and the windscreen. Both pilots reported that there were no preaccident mechanical malfunctions or failures with their airplanes that would have precluded normal operation.
