Probable Cause
The Aviation and Railway Accident Investigation Board (ARAIB) determined that the cause of the runway excursion was that the rudder failure was not recognized by the pilots during flight and as well as during landing roll. Contributing factors were that the rudder was failing to respond to the pilots' rudder pedal input and that after departing from the runway, no appropriate alternative measure was taken to control the aircraft direction.
