The NTSB's narrative for the Cessna 172S final · quoted from the NTSB record

The flight instructor and student pilot were parked with the airplane's engine running when the airplane began to move forward and to the right. The instructor stated that upon noticing the forward movement, he applied the brakes. He reported that the right rudder/brake pedal was positioned further forward than the left pedal, and upon application of brakes, the right turn increased before the airplane impacted another occupied airplane parked on the ramp, resulting in substantial damage to both. The student pilot reported that he noticed the airplane's movement and tried to alert the instructor; however, the instructor appeared to be distracted. Postaccident examination of the brake system revealed no anomalies that would have precluded normal operation. It is likely that the airplane's nose wheel was initially displaced to the right, which resulted in the airplane's right turn.
