The first officer, not the captain, was flying AirAsia Flight 8501 when it crashed.
Even as hope faded for the family of the pilot flying the missing AirAsia plane, a despairing message came from his daughter.
Investigators said the system that helps control the movement of the aircraft's rudder had a cracked solder joint that malfunctioned four times during the flight.
Nine months after Malaysia Airlines Flight 370 disappeared shortly after takeoff from Kuala Lumpur, Indonesia AirAsia Flight 8501, an Airbus A320 airliner carrying 162 people, disappeared from radar screens early Sunday, about 40 minutes after leaving the Indonesian city of Surabaya en route to Singapore. Till Monday, there were no signs of the missing plane. The story of AirAsia flight QZ8501 sounds remarkably similar to that of Malaysia Airlines MH370, which remains missing nearly 10 months after it disappeared from radar screens on a flight between Kuala Lumpur, Malaysia, and Beijing.
An AirAsia flight from Indonesia to Singapore with 162 people aboard reportedly went missing on Sunday morning after losing contact with air traffic controllers.
