Shortly after takeoff from Taipei Songshan Airport, the crew of TransAsia Airways Flight 235 shut down the wrong engine in response to a flameout, leading to a crash that resulted in 43 deaths.

Taipei Songshan Airport is a city airport and military airbase located in Songshan District, Taipei, Taiwan. The airport covers an area of 182 hectares.

TransAsia Airways Flight 235 was a domestic flight from Taipei to Kinmen, Taiwan. On 4 February 2015, the aircraft serving the flight, a 10-month-old ATR 72-600, crashed into the Keelung River around 5 km from Taipei Songshan Airport, where the aircraft had just departed from. On board were 58 people, 15 of whom survived with injuries.

In aviation, a flameout is the run-down of a jet engine or other turbine engine due to the extinguishment of the flame in its combustor. The loss of flame can have a variety of causes, such as fuel starvation, excessive altitude, compressor stall, foreign object damage deriving from birds, hail, or volcanic ash, severe precipitation, mechanical failure, or very low ambient temperatures.
