## Probable cause

the mechanical separation of the left engine beta control linkage during landing rollout, which resulted in asymmetrical decelerative action and the pilot's subsequent inability to maintain directional control.  The separation of the linkage was due to the airline's inadequate inspection and quality assurance procedures.  An inoperative windsock pivot point, which resulted in faulty wind direction information to the flight crew was a factor in this accident.
