aircraft
B-1816 is Delivered to china airlines on February 2, 1991 as an airbus a300-600, at the time of the accident, the aircraft is 3.5 years old with 8,572 hours and 3,910 takeoff and landing cycles. It was one of the newer models of the airbus A300, but it's not equipped with an go around system override, which airbus released a few months ago due to previous 10 incidents with the A300 Go around system.

Cause
while the aircraft is making a ILS approach to runway 34, then, the first officer increased power to the engines and accidentally engaged the go around system, then he tries to push the nose down, following the instructions of the captain, as the F/O keeps pushing down on the control column, the THS (Horizontal Stabilizer) Moved to the full nose up position. the crew continued the approach until the captain calls for a go around, so he increased thrust on the engines, but with the sudden acceleration, the plane pitched up even more, and the capt and F/O failed to recover the plane, and it crashed. one of the causes of this crash is because in 10 previous A300 incidents, the pilots accidentally activates the Go around mode, and then airbus posted a Service bulletin that recommend airlines to equip a new system to the A300 that can override the go around mode, but because its recommend, so china airlines did not update the systems. and another cause is that china airlines don't have a A300 simulator in Taipei, so their simulation trainings take place in Bangkok, where there is an override to the Go around mode.
