Narrative:

Collision with a chain link fence due to: student unfamiliar with braking system in this particular PA28-180 (no toe brakes on either pilot or copilot's side). Throttle set at too high a power setting at engine start up. After completing a thorough preflight using a checklist, the engine was started by the student and the plane lurched forward. I commanded the student to apply the brake, which he said would not function. I applied the hand brake, full back pressure, and full right rudder to avoid the nearby fence and commanded the student to chop the power. The student hesitated. The aircraft had turned 90 degrees but the outer 2 ft of the left wing hit the fence and the nose veered into it destroying the propeller. The entire incident took less than 5 seconds.
