Pushback for departure was accomplished at 20:34 and the crew received taxi instructions for runway 3C.

PROBABLE CAUSE: "The flight crew's failure to use the taxi checklist to ensure that the flaps and slats were extended for take-off. Contributing the accident was the absence of electrical power to the airplane take-off warning system which thus did not warn the flight crew that the airplane was not configured properly for take-off. The reason for the absence of electrical power could not be determined."
