| Executive Summary: | After pushback, a Boeing 747-300 experienced braking failure. The captain was able to maneuver the airplane into a controlled collision with a boarding finger rather than collide with another airplane. It is considered that the probable cause of this incident was the fact that the electrically driven hydraulic pump (ACP) was not manually connected again after its switch automatically released as a result of the initiation of the starting process of engine number 4 and once that starting process had not been completed. Contributing factors to this incident were: - The behavior of some passengers, that were complaining, refusing to fly and standing in the passenger cabin and that made the chief cabin attendant to enter at least twice the cockpit to inform the pilot in command. - The failure to complete the “after start” checklist detailed in the Operations Manual of the operator. - The failure to connect the alternative or emergency hydraulic systems when the brake failure was noticed. |
