Circumstances:
The captain (who was the pilot flying) initiated the takeoff roll, and the airplane accelerated normally. According to the cockpit voice recorder (CVR) transcript, the first officer made the “V1” and then “rotate” callouts. According to the captain (in a postaccident interview), when he pulled back on the control column to rotate the airplane, “nothing happened,” and the control column felt like it “was in concrete” and “frozen.” The CVR captured that the first officer subsequently made the “V2” callout, then the captain said “come on” in a strained voice. Both pilots recalled in postaccident interviews that they both attempted to pull back on the controls, but the airplane did not rotate. The CVR captured that the first officer called out “abort.” The first officer pulled the thrust levers to idle and applied the brakes, and the captain deployed the thrust reversers. (See “Execution of Rejected Takeoff” for more information.) The airplane overran the departure end of the runway and continued through the airport perimeter fence and across a road, striking electrical distribution lines and trees before coming to rest in a pasture, where a postcrash fire ensued. The pilots, two additional crewmembers, and all passengers evacuated the airplane. Two passengers received serious injuries, and one received a minor injury. The airplane was totally destroyed by a post crash fire.
Probable cause:
The jammed condition of both elevators, which resulted from exposure to localized, dynamic high wind while the airplane was parked and prevented the airplane from rotating during the takeoff roll. Also causal was the failure of Everts Air Cargo, the pilots’ primary employer, to maintain awareness of Boeing-issued, required updates for its manuals, which resulted in the pilots not receiving the procedures and training that addressed the requirement to visually verify during the preflight checks that the elevators are not jammed.
Final Report:
