On August 24, 2001, Air Transat Flight 236 leaks large amounts of fuel, but the pilots discount the ECAM warnings and the aircraft runs out of fuel. The pilots glide the aircraft to a naval base in the Azores where it lands safely. The post-incident investigation determines that improper maintenance actions during an engine change caused a hydraulic oil pipe and a fuel pipe to touch each other, resulting in the fracture of the fuel pipe.
