**3.5 Crash of an Airbus model 330: 243 aircraft**

On August 24th, 2001, Air Transat Flight TSC236, an Airbus Model 330–243 aircraft, was on a scheduled flight from Toronto, Canada, to Lisbon, Portugal [16]. A fuel leak in the right engine was not detected by the flight crew. Right engine eventually flamed out, followed by the left engine too. The flight crew initiated a diversion from the planned route for a landing at Lajes Airport on Terceira Island in the Azores. Assisted by radar vectors from Lajes air traffic control, the crew carried out an all-engine out visual approach and landing at night, in good visual weather conditions. Sixteen passengers and two cabin-crew members received injuries during the emergency evacuation. The aircraft suffered structural damage to the fuselage and to the main landing gear. The accident investigators determined that the fuel leak was caused by fuel line cracking that resulted from interference between the fuel line and a hydraulic line on the right engine. The interference was caused by an incomplete service bulletin incorporation creating a mismatch between the fuel and hydraulic lines during replacement of the right engine.
