China Airlines Flight 140 was a regularly scheduled passenger flight from Chiang Kai-shek International Airport (serving Taipei, Taiwan) to Nagoya Airport in Nagoya, Japan.On 26 April 1994, the Airbus A300B4-622R was completing a routine flight and approach, when, just seconds before landing at Nagoya Airport, the takeoff/go-around setting (TO/GA) was inadvertently triggered. The pilots attempted to pitch the aircraft down while the autopilot, which was not disabled, was pitching the aircraft up. The aircraft ultimately stalled and crashed into the ground, killing 264 of the 271 people on board.

To date, the accident remains the deadliest accident in the history of China Airlines, and the second-deadliest aviation accident on Japanese soil, behind Japan Airlines Flight 123. It is also the third-deadliest aviation accident or incident involving an Airbus A300, after Iran Air Flight 655 and later American Airlines Flight 587.
