Pilots, rudder faulted in crash

Investigators did not pinpoint a single underlying reason why the AirAsia flight disappeared from radar

Chronic problems with a faulty rudder system and the way pilots tried to respond were among a string of factors contributing to the crash of an Indonesian AirAsia jet last year that killed all 162 on board, investigators said on Tuesday.

The Airbus A320 crashed into the Java Sea on Dec 28, less than halfway into a two-hour flight from Indonesia's second-biggest city of Surabaya to Singapore.
