> The National Transportation Safety Board determines the probable cause(s) of this incident to be:
>The first officer's failure to attain the proper touchdown point and the flight crew's failure to call for a go-around, which resulted in the airplane landing more than halfway down the runway. Contributing to the incident were, the first officer's initiation of the landing flare at a relatively high altitude and his delay in reducing the throttles to idle, the captain's delay in manually deploying the speed brakes after touchdown, the captain's lack of command authority, and a lack of robust training provided by the operator to support the flight crew's decision-making concerning when to call for a go-around.
