A Canadian domestic flight involving a Boeing 767 faced a critical situation shortly after takeoff when both engines failed due to a fuel measurement error. The aircraft was in the process of transitioning from the imperial system (which uses pounds and gallons) to the metric system (which uses kilograms and liters) for fuel calculations. The fuel amount was mistakenly calculated in pounds instead of kilograms, resulting in the plane carrying only about half the fuel needed for the flight. This error occurred because the crew used a conversion factor of 1.77 pounds per liter instead of the correct 0.8 kilograms per liter, which was appropriate for the aircraft’s fuel system. Despite multiple checks, the error went unnoticed, leading to a dangerous situation where the plane took off with insufficient fuel. The pilots were not trained to handle a scenario involving the simultaneous failure of both engines, as no such emergency checklist existed at Air Canada at the time. The loss of both engines also caused the aircraft to lose its main hydraulics and part of its instrumentation, leaving the cockpit in a state where the crew had to rely on improvisation. However, the captain had practiced gliding during leisure time, a skill that proved crucial in controlling the aircraft without engine power. This personal training, outside of company-provided instruction, became the most valuable asset for the crew during the emergency. The aircraft was guided to an old military airfield that had been converted into a car racing track. At the time of the landing, a car race was in progress on the same field, with vehicles, spectators, and a section of the track blocked for the event. Despite these challenges, the aircraft landed safely without causing any injuries to the passengers or people on the ground. The incident prompted significant changes in Air Canada’s procedures. The company quickly converted all its aircraft to the metric system and eliminated manual conversions between pounds and kilograms during refueling. Air Canada also updated its minimum equipment requirements before takeoff, especially regarding fuel measurement systems. Eventually, a checklist was created for the simultaneous loss of both engines. The affected aircraft, after being repaired, continued to operate for another twenty-five years with the same airline.
