Indonesia AirAsia Flight 8501 was a scheduled international passenger flight operated by Indonesia AirAsia from Surabaya, Indonesia, to Singapore. On 28 December 2014, the Airbus A320-216 flying the route crashed into the Java Sea, killing all 162 of the people on board. When search operations ended in March 2015, only 116 bodies had been recovered. As of 2026, this is the only fatal accident involving AirAsia and its affiliates.
In December 2015, the Indonesian National Transportation Safety Committee (KNKT or NTSC) released a report concluding that a non-critical malfunction in the rudder control system prompted the captain to perform a non-standard reset of the on-board flight control computers.
