The flight was also included in a Mayday Season 6 (2007) Science of Disaster special titled "Who's Flying the Plane?" [8] This was later cancelled and replaced by F-2005-195. [Portugal Accident Investigation Final Report, §3.1], May Day: Flying on Empty, Cineflix, Episode 6, Season 1, 8 October 2003 (Air Transat 236), Portugal Accident Investigation Final Report, All Engines-out Landing Due to Fuel Exhaustion, Air Transat, Airbus A330-243 marks C-GITS, Lajes, Azores, Portugal, 24 August 2001. The story of this plane was a major fuel leak on board. [§1.19.3.3.] Although the existence of the optional Rolls-Royce SB RB.211-29-C625 became known during the engine change, the SB was not reviewed during or following the installation of the hydraulic pump, which negated a safety defence that should have prevented the mismatched installation. Moises Tvtv. The fuel logs had shown normal fuel burns during the first four hours of the flight, the last normal reading having taken place at 04:57 [¶1.6.5.2]. [4] It was powered by two Rolls-Royce Trent 772B-60 engines capable of delivering 71,100 lbf (316 kN) thrust each.

Everything here is from the references shown below, with a few comments in an alternate color. A … 49:00. The problem wasn't covered in the flight manual. My first concern is usually fire and then to the age-old question: do I have enough fuel to make it to land? At 06:13 the right engine flamed out. If it differs appreciably from the fuel decrease in the tanks, you have some investigating to do. They chalked this up as another computer problem. The plane suffered structural damage to the main landing gear and the lower fuselage. Hours later they got a fuel imbalance warning, showing the left wing heavy. This action resulted in the Fuel ECAM page being displayed and the crew becoming aware of a fuel imbalance between the left and right inner-wing tanks. Moises Tvtv. The ALL ENG FLAME OUT procedure was completed by the crew and an engines-out descent profile was flown towards Lajes. During the turn, the aircraft was configured with leading-edge slats out and landing gear down for the landing. Flight TS 236 took off from Toronto at 00:52 (UTC) on Friday, August 24, 2001 (local time: 20:52 (ET) on Thursday, August 23), bound for Lisbon, Portugal.

[§1.19.3.5] The crew stated that because there were no other signs of a fuel loss, other than the lower than expected quantity of fuel on board, and because there had been no other ECAM warnings or cautions both pilots believed that the problem was a computer fault. All Engines-out Landing Due to Fuel Exhaustion . Military air traffic controllers guided the aircraft to the airport with their radar system. Figure: Right engine fuel and hydraulic lines, from Portugal Accident Investigation Final Report, §1.6.3. Five minutes later the crew concerned about the lower-that-expected fuel quantity indication, decided … See Fuel Leak Inflight for more on this. [2][Note 1], At 04:38 UTC, the aircraft began to leak fuel through a fracture which had developed in a fuel line to the No. Although a clearance between the fuel tube and hydraulic tube was achieved during installation by applying some force, the pressurization of the hydraulic line forced the hydraulic tube back to its natural position and eliminated the clearance. The assumed the issue was a computer indication problem, not an engine problem. [Portugal Accident Investigation Final Report, §1.16.2], [Portugal Accident Investigation Final Report], The engine oil indications were the unusual combination of low oil temperature, low oil quantity, and high oil pressure.

Portugal Accident Investigation Final Report. [2]:7,23 Although these readings were an indirect result of the fuel leak, there was no reason for the pilots to consider that as a cause. The Captain advised Lajes that he was conducting a left 360-degree turn in order to lose altitude. They should have looked at their total fuel quantity and realized they were losing fuel faster than they were burning it, it had to be going someplace. The crew did not correctly evaluate the situation before taking action. The Airbus A330 ran out of fuel due to a fuel leak caused by improper maintenance. Fourteen passengers and two crew members suffered minor injuries, while two passengers suffered serious injuries during the evacuation of the aircraft.

It is said that a fuel crossflow on the Airbus 330 happens very quickly and effectively, but for this crew it did not. At 06:23, the First Officer declared a "Mayday" with Santa Maria Oceanic Control, and at 06:26, when the aircraft was 65 nautical miles from the Lajes airport and at an altitude of about FL 345, the left engine flamed out. By 05:48, the crew advised Santa Maria Oceanic air traffic control that the flight was diverting due to a fuel shortage; the fuel on board had reduced to 7.0 tons. Air Transat admitted as much and was fined heavily. This caused a higher than normal fuel flow through the fuel-oil heat exchanger (FOHE), which in turn led to a drop in oil temperature and a rise in oil pressure for the No. According to the crew, the cross feed from the right tank was established to use up the fuel from the right wing and to counter the possibility that the fuel loss was the result of a leak in the right wing tanks. Ten minutes later, the crew sent a Mayday to Santa Maria Oceanic air traffic control. Because the anti-skid and brake modulation systems were inoperative, the eight main wheels locked up; the tires abraded and fully deflated within 450 feet (140 m).[2]:11. These selections established cross feed of the fuel in the right wing tanks to both engines. The crew notified Santa Maria control that the engine had flamed out and that the flight was descending. Conducting the FUEL IMBALANCE procedure by memory negated the defence of the Caution note in the FUEL IMBALANCE checklist that may have caused the crew to consider timely actioning of the FUEL LEAK procedure.

According to the crew, the flight progressed normally until after crossing 30° West and at 05:03 when they observed unusual engine oil indications on the Number 2 (right) engine (Rolls-Royce RB211 Trent 772B)3. Moises Tvtv. Although there were a number of other indications that a significant fuel loss was occurring, the crew did not conclude that a fuel leak situation existed – not actioning the FUEL LEAK procedure was the key factor that led to the fuel exhaustion.
