Adam Air Flight 574 (KI574 or DHI574) was a scheduled domestic passenger flight operated by Adam Air between the Indonesian cities of Surabaya (SUB) and Manado (MDC) that crashed into the Makassar Strait near Polewali in Sulawesi on 1 January 2007. All 102 people on board died, the highest death toll of any aviation accident involving a Boeing 737-400 and the third-deadliest aviation incident in 2007, behind TAM Airlines Flight 3054 and Kenya Airways Flight 507. A national investigation was launched into the disaster. The final report, released on 25 March 2008, concluded that the pilots lost control of the aircraft after they became preoccupied with troubleshooting the inertial navigation system and inadvertently disconnected the autopilot. It was the only fatal accident for Adam Air in the 5-year history of the company.
The crash is one of several transportation accidents, including the subsequent non-fatal crash of Adam Air Flight 172, which among them have resulted in large-scale transport safety reforms in Indonesia, as well as the United States downgrading its safety rating of Indonesian aviation, and all the entire Indonesian airlines has been added to the list of air carriers banned in the EU. Adam Air was then subsequently banned from flying by the Indonesian government few years later, and then declared bankruptcy.
The aircraft involved, Boeing 737-4Q8 serial number 24070, registration PK-KKW, was manufactured in 1989. Prior to service with Adam Air, owned by ILFC the aircraft had been leased to seven airlines: Dan-Air, British Airways, GB Airways, Transaero, WFBN, Air One and Jat Airways. Provided with twin CFM56-3C1 powerplants, the plane had around 50,000 hours flying and was last evaluated and declared airworthy by the Indonesian transport ministry on 25 December 2005. It was due to be checked again in late January 2007. The Surabaya airport duty manager said that there were no technical problems with the aircraft prior to departure.
