Air Canada Flight 759: A Close Call with Disaster


Air travel is considered one of the safest modes of transportation, thanks to rigorous safety protocols and advanced technology. However, even in the highly regulated aviation industry, accidents and near-misses can occur, reminding us of the importance of constant vigilance and adherence to safety procedures. One such incident that sent shockwaves through the aviation community was the close call involving Air Canada Flight 759, which narrowly avoided disaster by mere meters. In this blog, we will delve into the details of this harrowing event, examining the factors that led to the near-catastrophe and the lessons learned from it.

On the night of July 7, 2017, Air Canada Flight 759, an Airbus A320, was scheduled to land at San Francisco International Airport (SFO) after a flight from Toronto Pearson International Airport. However, as the aircraft approached SFO’s runway 28R for landing, chaos ensued. Instead of lining up with the runway, the aircraft descended dangerously low over a taxiway where four fully loaded airplanes were awaiting takeoff clearance.

The aircraft came within a mere 18 meters (about 60 feet) of disaster, narrowly avoiding a catastrophic collision with the waiting planes. The pilots of Flight 759 realized their mistake at the last moment and initiated a go-around, pulling the aircraft up and away from the taxiway. The flight eventually landed safely on its second approach, but the incident left a lasting impact on all involved.

Several factors contributed to the near-disaster of Air Canada Flight 759. One key factor was the misidentification of the taxiway as the runway by the flight crew. The taxiway, which ran parallel to the intended runway, was brightly lit and lined with runway lights, creating a visual illusion that misled the pilots during their approach.

Additionally, fatigue may have played a role in the pilots’ misjudgment. The flight crew had been awake for more than 19 hours due to a scheduling error, leading to impaired cognitive function and decision-making abilities. This highlights the importance of managing crew fatigue and ensuring that pilots are well-rested before undertaking flight operations.

Furthermore, communication breakdowns between the flight crew and air traffic controllers may have compounded the confusion during the approach. The crew’s failure to acknowledge critical instructions from the tower, such as the presence of other aircraft on the taxiway, further exacerbated the situation.

The incident involving Air Canada Flight 759 served as a wake-up call for the aviation industry, prompting a revaluation of safety procedures and training protocols. Several lessons emerged from the incident, aimed at preventing similar occurrences in the future:

  1. Enhanced Situational Awareness: Pilots must maintain a high level of situational awareness during all phases of flight, especially during critical moments such as approach and landing. Training programs should emphasize the importance of visual scanning techniques and encourage pilots to cross-reference navigational aids to confirm their position.
  2. Crew Resource Management (CRM): Effective communication and teamwork are essential components of safe flight operations. Crew resource management training programs should focus on fostering open communication channels and encouraging assertiveness among flight crew members to address potential errors or deviations from standard procedures.
  3. Fatigue Management: Airlines must prioritize crew fatigue management to ensure that pilots are well-rested and alert during flight operations. Scheduling practices should adhere to regulatory guidelines and take into account factors such as circadian rhythms and restorative sleep.
  4. Technology Integration: Advancements in aviation technology, such as enhanced ground proximity warning systems and cockpit displays, can provide additional layers of safety during flight operations. Airlines should invest in the latest technology and ensure that pilots receive comprehensive training on its use.

The near-disaster of Air Canada Flight 759 serves as a stark reminder of the importance of safety in aviation and the need for continuous improvement in training, procedures, and technology. While the incident narrowly avoided catastrophe, it underscored the potential consequences of human error and organizational shortcomings in a high-stakes environment. By learning from past mistakes and implementing proactive safety measures, the aviation industry can strive to maintain its unparalleled safety record and ensure the well-being of passengers and crew alike.
