Phoenix - Tucson

During approach, a fire erupted in the wheel well of the 22-year old airplane. The fire burned thru the hydraulic lines rendering the a, b, and standby hydraulic systems inoperative. The crew landed the airplane using the emergency manual reversion flight control system. However, the airplane was unable to stop on the runway because of the previous failures of the check valves in the backup hydraulic accumulator pressure systems for the #2 thrust reverser and the inboard pair of wheel brakes. During the 2 minutes rollout, the airplane traversed 14,000 feet, overran the runway end, and collided with a concrete structure which collapsed the nose gear. The airplane had recently undergone a 'C' check during which the operator's mechanics failed to observe and repair an electric wire which had been chafing against a hydraulic line. On the accident flight the energized wire arced, punctured the line, and ignited the escaping hydraulic fluid. The hydraulic check valves had failed earlier due to mechanical wear.
