In 2001, jet ran out of fuel over Atlantic; pilot glided 306 people to safety

A routine transatlantic journey from Canada to Portugal became a fight for survival when an Air Transat passenger jet lost both its engines over the Atlantic Ocean in August 2001. With no engine power and land still some distance away, Captain Robert Piché and First Officer Dirk DeJager had to guide the aircraft towards an airport in the Azores, relying on the plane's ability to glide. All 306 people aboard survived the emergency landing, although several passengers and crew members were injured. According to the Portuguese aviation accident investigation report, CBC News and the Aviation Safety Network, the Airbus A330 ran out of fuel because of a leak that developed during the flight. The incident, involving Air Transat Flight 236, later became known as the Azores Glider and remains one of the most remarkable examples of an unpowered passenger aircraft landing.The flight departed Toronto Pearson International Airport on August 23, 2001, bound for Lisbon, Portugal, with 293 passengers and 13 crew members aboard. The aircraft, an Airbus A330-243, was just over two years old. It was commanded by Piché, an experienced pilot with more than 16,000 flight hours, alongside first officer DeJager. Around four hours into the journey, a fracture developed in a fuel line connected to the aircraft's right engine. The resulting leak caused fuel to escape at an alarming rate, eventually leaving the aircraft with far less fuel than its instruments and flight plan initially suggested. The crew first noticed unusual oil temperature and pressure readings in the right engine. However, the warnings were not immediately identified as signs of a fuel leak. The pilots contacted the airline's maintenance control centre and were advised to monitor the situation.A subsequent fuel imbalance warning prompted the crew to transfer fuel between the aircraft's tanks. However, the procedure inadvertently sent more fuel towards the leaking engine, accelerating the loss. By the time the pilots recognised the seriousness of the situation, a substantial amount of fuel had already been lost. At 5.45 UTC on August 24, the pilots decided to divert to Lajes Air Base on Terceira Island in the Azores, a Portuguese archipelago in the Atlantic.At 6.13 UTC, the right engine stopped after running out of fuel. The aircraft was still approximately 150 nautical miles from Lajes. The crew continued descending towards the island, but the situation deteriorated further when the left engine also shut down at 6.26 UTC, leaving the aircraft without any engine power. With both engines out, the Airbus became a glider. Its emergency ram air turbine automatically deployed, providing enough electrical and hydraulic power to operate essential flight controls and instruments. However, several other systems, including the normal braking and flap systems, were no longer available.A 19-minute glide towards the runwayThe aircraft was now around 65 nautical miles from Lajes, and the pilots had to make every remaining manoeuvre count. Air traffic controllers at the military airbase used radar to guide the aircraft towards the runway. Piché and DeJager worked together to manage the descent and maintain enough altitude to reach the airport. With the aircraft losing height rapidly, the captain also performed a series of turns to reduce its altitude and line it up for landing.After approximately 19 minutes without engine power, the aircraft reached Lajes Airport at 6.45 UTC on August 24. It touched down on Runway 33 at around 200 knots, considerably faster than a normal landing speed. The landing was hard, and the aircraft bounced once before touching down again. With its antiskid braking system unavailable, the main landing gear wheels locked, causing the tyres to deflate and sustain severe damage as the aircraft travelled along the runway. It eventually came to a stop, using much of the available runway.The emergency evacuation began immediately. All 306 people survived, although 16 passengers and two crew members sustained injuries, including two passengers who were seriously injured but not in a life-threatening condition. The aircraft itself suffered substantial damage to its landing gear and lower fuselage.What caused the aircraft to run out of fuel?An investigation led by Portugal's Aviation Accidents Prevention and Investigation Department, with assistance from the Transportation Safety Board of Canada, examined the circumstances behind the incident. Investigators traced the fuel leak to a maintenance error involving incompatible parts fitted during the replacement of the aircraft's right engine. A hydraulic line had been installed too close to a fuel line, allowing the two to rub against each other during operation. The friction eventually caused a crack in the fuel line, through which fuel escaped.The investigation also identified shortcomings in how the cockpit crew interpreted the fuel warnings and responded to the imbalance. Their decision to follow the fuel imbalance procedure without recognising the possibility of a leak contributed to the loss of fuel. Air Transat accepted responsibility for the maintenance-related failure and was fined C$250,000 by Canadian authorities in September 2001. The accident also prompted changes to aircraft operating procedures and fuel-leak warnings to help prevent similar incidents.Recognition for the flight crewThe successful landing brought international attention to Piché and DeJager. In 2002, Piché received the Air Line Pilots Association's Superior Airmanship Award in recognition of his handling of the emergency. The incident also became the subject of documentaries, aviation programmes and the 2010 Canadian biographical film Piché: The Landing of a Man, which depicts the captain's life and the events surrounding Flight 236.Often remembered as the Azores Glider, the flight remains a landmark in commercial aviation. Its 65-nautical-mile unpowered journey demonstrated the importance of cockpit coordination, emergency decision-making and the ability of flight crews to respond under extraordinary circumstances.
