The Boeing 767 en route from Montreal to Edmonton experienced a fuel exhaustion due to a series of errors and miscalculations. Fortunately, the skilled pilots were able to glide the aircraft safely to the ground, leading to this incident being known as the “Gimli Glider.”
So, what were the key factors that led to the crash of Flight 143? One of the main reasons was the conversion error in fuel measurement units between kilograms and pounds. The refueling crew had mistakenly filled half the required amount of fuel, which was already converted into kilograms instead of pounds, leading to a disastrous situation mid-flight.
1. Conversion error in fuel measurement units: The refueling crew miscalculated the fuel quantity, converting it from pounds to kilograms incorrectly. As a result, only half the required fuel was loaded on the aircraft.
2. Incorrect fuel gauge readings: The pilots relied on the aircraft’s fuel quantity gauge, which showed that there was sufficient fuel for the journey. However, due to the conversion error, the gauge readings were inaccurate, and the actual fuel on board was much lower than indicated.
3. Lack of communication and coordination: There was a lack of effective communication and coordination between the pilots, the refueling crew, and the maintenance team. This led to the incorrect fuel quantity being loaded onto the aircraft and the failure to detect the conversion error.
4. Inadequate training and procedures: The pilots were not adequately trained to handle fuel conversion errors and emergency glides. The incident exposed gaps in training and procedures concerning fuel management and emergency procedures.
In conclusion, the crash of Flight 143 was a result of a series of errors, including the conversion error in fuel measurement units, incorrect fuel gauge readings, lack of communication and coordination, and inadequate training and procedures. Despite these challenges, the successful glide landing by the experienced pilots prevented a catastrophic outcome and highlights the importance of effective training, communication, and error prevention in aviation safety.
Background of Flight 143
Flight 143, also known as Air Canada Flight 143, was a scheduled domestic passenger flight from Montreal, Quebec, to Edmonton, Alberta. The flight was operated by Air Canada, one of the major airlines in Canada. On July 23, 1983, the flight was being operated by a Boeing 767-200 with registration C-GAUN.
At the time of the accident, Flight 143 had a total of 69 people on board, including 61 passengers and 8 crew members. The captain of the flight was Captain Robert Pearson, a highly experienced pilot with over 15,000 hours of flight time. The first officer was Maurice Quintal, who had over 8,000 hours of flight time.
Flight 143 departed Montreal at 8:41 AM local time, and everything seemed to be going smoothly during the initial part of the flight. However, about 23 minutes into the flight, the aircraft experienced a major fuel system failure, which led to the loss of all engines.
It was later determined that the accident was caused by a series of errors and miscalculations. The ground crew had mistakenly filled the aircraft’s fuel tanks with a mixture of jet fuel and gasoline, instead of the required full supply of jet fuel. This mistake resulted in the aircraft running out of fuel mid-flight.
Causes of the Crash
The crash of flight 143 was attributed to a combination of human error and mechanical failure. One of the key factors leading to the accident was the incorrect conversion of fuel quantity from pounds to kilograms during the refueling process. This error resulted in the aircraft having only half the amount of fuel required for the flight.
Another contributing factor was the failure of the aircraft’s fuel gauges. The meters were not properly calibrated, making it difficult for the pilot and co-pilot to accurately determine the amount of fuel remaining. This further exacerbated the fuel shortage issue and prevented the crew from recognizing the problem in time.
The flight crew also played a role in the crash. The pilot and co-pilot failed to follow proper checklist procedures and failed to notice the low fuel levels and the weight discrepancy caused by the incorrect conversion. Their lack of attention to detail and failure to communicate effectively contributed to the tragedy.
Additionally, the lack of clear communication between the ground crew and the flight crew also played a part in the crash. The ground crew was aware of the fuel shortage but did not effectively communicate this information to the flight crew. This lack of communication prevented the crew from taking appropriate action in a timely manner.
In conclusion, the crash of flight 143 was caused by a combination of errors and failures. Human error, mechanical failure, and communication breakdowns all played a part in the tragic event. It serves as a reminder of the importance of thorough procedures, double-checking calculations, and effective communication in aviation safety.
