Probable cause
a manufacturing defect in a clutch mechanism that prevented the speedbrakes from automatically deploying after touchdown, and the captain’s failure to monitor and extend the speedbrakes manually. Also causal was the failure of the thrust reversers to deploy when initially commanded. Contributing to the incident was the captain’s failure to confirm speedbrake extension before announcing their deployment, and his distraction caused by the thrust reversers’ failure to initially deploy after landing.
