Adam Air Flight 574Monday January 1, 2007
While flying at FL350 the airliner went missing between Surabaya and Manado in poor weather conditions after the pilot reported strong winds. Wreckage was found 5 miles south of Parepare. The accident was caused by the autopilot being accidentally disconnected. The two pilots had been trying to fix a problem with the plane's navigation instruments when they disconnected the autopilot and lost control of the plane. Without the autopilot, the plane went out of control, listing to the right and pitching down. The IRS navigation system was repeatedly reported malfunctioning but was never repaired. This is what initially distracted the crew.
