It has also helped the industry to improve its operational practices.

The Day of the Incident: A Detailed Timeline

Alright, let's go back to that fateful day: July 23, 1983. Air Canada Flight 143 was scheduled to fly from Montreal to Edmonton, with a stop in Ottawa. The plane, a brand-new Boeing 767, was ready for its journey. The flight crew was experienced, the weather was clear. No one could have predicted what was about to happen. The drama unfolded in stages, starting with the fuel gauges. When the fuel quantity indicating system (FQIS) failed, the ground crew had to manually calculate the amount of fuel needed. Here is a breakdown of what happened when Air Canada Flight 143 was in the air, step by step:

1. Fueling Up: The ground crew used a manual calculation to determine the amount of fuel needed. This calculation contained a significant error due to a misunderstanding of the units of measurement. The fuel quantity indicating system (FQIS) was not working. This added to the complexity of the situation.
2. Takeoff: The plane took off from Montreal. The crew was unaware of the fuel shortage. Everything seemed normal during the initial part of the flight.
3. Mid-Air Warning: About halfway through the flight, the crew received a warning signal indicating low fuel pressure. This was the first sign of trouble. The pilots and crew quickly began to assess the situation.
4. Engine Failure: Shortly after the warning, the first engine failed. The pilots tried to restart the engine, but it didn't work. They knew they were in a serious situation.
5. Second Engine Failure: Not long after the first engine failed, the second engine cut out. Now, the plane was gliding without any engine power. The pilots had to act quickly to find a suitable landing spot.
6. Emergency Landing: With no power, the pilots had to glide the aircraft to a nearby airfield. Fortunately, they were able to land at a former Royal Canadian Air Force base at Gimli, Manitoba.
7. The Landing: The landing was successful, but the plane's nose gear collapsed upon touchdown. The plane slid down the runway. It eventually came to a stop in a safe position.
8. Evacuation: All passengers and crew were safely evacuated from the plane. No one was seriously injured, which was a miracle given the circumstances.

The entire event, from the first warning to the safe landing, happened within a matter of minutes. The flight crew's quick thinking, training, and experience were key to saving the lives of everyone on board. This dramatic timeline underscores the importance of every step in flight operations. It also shows the importance of quick thinking in crisis situations. The Gimli Glider story is a testament to human resilience and skill.

The Root Cause: A Series of Errors

So, what exactly went wrong? The primary cause of the Air Canada Flight 143 incident was a series of errors, which, when combined, led to the fuel crisis. It wasn't just one mistake; it was a cascade of several problems. The key factor was a miscalculation of the fuel needed for the flight. The ground crew was using the wrong unit of measurement. They were using pounds instead of kilograms when calculating the fuel. This led to a significant underestimation of the fuel required. This simple error had disastrous consequences. Let's break down the main reasons:

• Fuel Calculation Error: The most critical error was the miscalculation of fuel. The ground crew, due to a misunderstanding, filled the plane with significantly less fuel than needed. This was the trigger that set off the chain of events.
• Fuel Quantity Indication System (FQIS) Failure: The fuel gauges on the plane were not working correctly. This meant the pilots couldn't rely on the gauges to monitor the fuel level. It added to the reliance on the ground crew's calculation.
• Conversion Error: The Boeing 767 was new to Air Canada. The ground crew and the pilots weren't fully familiar with the new system. This lack of familiarity contributed to the confusion and errors.

These factors combined created a perfect storm of failures. The crew was not aware of the fuel shortage until it was too late. This highlighted the importance of thorough maintenance, correct procedures, and clear communication. The mistakes revealed by the investigation had an impact on aviation. It led to significant changes in training protocols. It also updated operational procedures across the industry. The Gimli Glider incident serves as a crucial case study in the importance of aviation safety standards.
