What Happened with Air Canada 759?

Air Canada flight 759 nearly became a catastrophic disaster when it mistook a taxiway for a runway at San Francisco International Airport (SFO). Imagine a fully loaded passenger plane descending towards a taxiway filled with other aircraft awaiting takeoff – that's precisely what happened. The flight, arriving from Toronto, was cleared to land on Runway 28R. However, as it approached, the pilots inadvertently lined up with Taxiway C, which was bustling with four fully loaded planes.

The incident unfolded late at night, around 11:56 PM PDT, when visibility was good. The Air Canada Airbus A320 was carrying 140 passengers and crew. As the plane descended, the pilots failed to recognize that they were not aligned with the runway. Instead, they were heading straight for a taxiway packed with aircraft. It wasn't until the very last moment that disaster was averted, thanks to quick thinking from both the Air Canada crew and air traffic control.

The Near Miss

As the Air Canada plane approached, some of the pilots on the taxiway noticed the impending danger. They began flashing their landing lights and even contacted air traffic control to raise the alarm. Meanwhile, on the Air Canada flight deck, the crew was still unaware of the imminent collision. It was only after multiple warnings and a go-around order from air traffic control that the pilots initiated a climb, narrowly avoiding a potentially catastrophic event.

According to the National Transportation Safety Board (NTSB) report, the Air Canada plane descended to as low as 85 feet above the ground before initiating the go-around. Can you imagine how close that was? Had the pilots not responded in time, the consequences could have been devastating. The incident prompted immediate investigations and raised serious questions about pilot fatigue, air traffic control procedures, and the overall safety of night landings.

Investigation and Findings

The NTSB conducted a thorough investigation into the Air Canada 759 near-crash to determine the contributing factors and prevent similar incidents in the future. The investigation involved analyzing flight data recorders, cockpit voice recorders, and conducting interviews with the flight crew, air traffic controllers, and other relevant personnel. The findings revealed a combination of factors that led to the near-disaster.

Key Contributing Factors

Several key factors contributed to the Air Canada 759 near-crash, painting a complex picture of how such an incident could occur. Let's break down these factors:

  1. Pilot Error: The primary cause was identified as pilot error. The pilots failed to properly identify the runway and maintain situational awareness during the approach. This error was compounded by fatigue and a lack of familiarity with the airport layout.
  2. Fatigue: The flight crew had been on duty for an extended period, which likely contributed to their diminished performance. Fatigue can significantly impair cognitive functions, making it harder to make critical decisions.
  3. Airport Layout: San Francisco International Airport has a complex layout, with closely spaced parallel runways and taxiways. This complexity can be particularly challenging during night landings, especially for pilots who are not familiar with the airport.
  4. Air Traffic Control Procedures: While the air traffic controllers did issue timely warnings, the investigation also examined whether the existing procedures could be improved to provide additional safeguards against similar errors.

Recommendations and Safety Measures

Following the investigation, the NTSB issued several recommendations aimed at improving aviation safety and preventing future incidents. These recommendations included:

  • Enhanced Training: Calls for enhanced training programs for pilots, focusing on night landings, airport familiarization, and the recognition of runway incursions.
  • Improved Airport Markings: Improvements to airport markings and lighting to make runways and taxiways more easily distinguishable, especially at night.
  • ATC Procedures: Reviewing and enhancing air traffic control procedures to provide additional layers of safety during critical phases of flight.
  • Fatigue Management: Implementing more robust fatigue management programs for flight crews to ensure they are well-rested and alert.
