Adam Air Flight 574
The increasing right bank goes completely unnoticed until Captain Widodo hears the bank angle warning. In response, he tells the first officer to put his IRS mode back on NAV. First Officer Susanto switches his mode back and attempts to take control of the aircraft to stop it from rolling into an inverted upset situation. Captain Widodo tells Susanto not to turn the aircraft, as he is still under the impression that the autopilot is keeping the aircraft on heading so that the IRS can realign itself. First Officer Susanto then tries to tell the captain that the aircraft is banking dangerously over to the right.
