## Analysis

THE TOE OF THE PILOTS LEFT BOOT WAS RUBBING ON THE DISPENSING HOPPER WHICH RESTRICTED APPLICATION OF RUDDER AND BRAKE. THIS RESULTED IN A LOSS OF CONTROL WHEN EXITING THE RUNWAY AND THE RESULTANT COLLISION WITH A SIGN. THE FIBERGLASS HOPPER HAD DEEP ABRASIONS JUST FORWARD AND ABOVE BOTH RUDDER PEDALS FROM THE TOES OF BOTH BOOTS RUBBING IN THE CONFINED AREA..
