A McDonnell Douglas DC-10-10 operated by United Airlines, suffered a landing accident at Denver-Stapleton Airport, CO.
As the captain was deploying reversers during landing, reversers no. 2 and 3 unlocked and deployed, but reverser no. 1 was binding and only moved to the unlocked position. The captain was not warned of this condition, though the second officer should have monitored the illumination of the reverser lights. The captain said he reached to check the no. 1 lever. At about that time, the aircraft yawed right. Despite immediate action by the captain, directional control of the aircraft was lost due to yawing caused by the inoperative thrust reverser. The aircraft continued off the runway, crossed two taxiways and the nose gear collapsed.
After stopping, evacuation was ordered. Evacuation slides deployed normally, but with the aircraft on its nose, use of slides at doors 4L & 4R was discontinued due to excessive vertical angle of slides.
Investigation revealed that after touchdown, engine no. 1 accelerated with forward thrust as no. 2 and 3 engines provided reverse thrust. At about the same time, the aircraft's nose lifted off the runway to a 4 degree attitude and the aircraft went off the runway.
Probable cause:
monitoring..inadequate..flight engineer
thrust reverser,cockpit control..bent
thrust reverser,cockpit control..binding(mechanical)
reversers..improper use of..pilot in command
directional control..not maintained..pilot in command
thrust reverser..inoperative
