AirAsia Flight 8501 QZ8501 was a scheduled international passenger flight, operated by AirAsia Group affiliate Indonesia AirAsia, from Surabaya, Indonesia, to Singapore. On 28 December 2014, the aircraft operating the route, an Airbus A320-216, crashed into the Java Sea during bad weather, killing all 155 passengers and seven crew on board. Two days after the crash, debris from the aircraft and human remains were found floating in the Java Sea. Searchers located wreckage on the sea floor beginning on 3 January, and the flight data recorder and cockpit voice recorder were recovered by 13 January. The search for bodies ended in March 2015 after recovery of 113 of the 162 bodies.
On 20 January 2015, it was reported that the aircraft had stalled during an abnormally steep climb and had been unable to recover.
The accident is the second-deadliest in Indonesian territory, behind Garuda Indonesia Flight 152 in 1997, the third-deadliest aviation incident in 2014, behind Malaysia Airlines Flight 370 and Malaysia Airlines Flight 17, and the second-deadliest involving an A320, behind TAM Airlines Flight 3054 in 2007. It was also AirAsia Group's first fatal accident in the 18-year history of the company
