Investigation
An Air Canada investigation concluded that the pilots and mechanics were at fault, although the Aviation Safety Board of Canada (predecessor of the modern Transportation Safety Board of Canada) found the airline at fault.
The safety board reported that Air Canada management was responsible for "corporate and equipment deficiencies". The report praised the flight and cabin crews for their "professionalism and skill". It noted that Air Canada "neglected to assign clearly and specifically the responsibility for calculating the fuel load in an abnormal situation", finding that the airline had failed to reallocate the task of checking fuel load that had been the responsibility of the flight engineer on older (three-crew) aircraft.
