Black box reports no icing problems in Buffalo crash

Investigators examining multiple plane crashes this year have their hands full, but today they announced that ice was not likely the cause of last month's fatal plane crash near Buffalo, N.Y., despite early media reports identifying ice as a potential culprit.



In reducing the emphasis on ice as a major cause of the crash, investigators are examining the role the pilot may have played in the accident. New flight data recorder information released today reveals that the controls of the plane were pulled back, which affected the aerodynamics of the wing.

The National Transportation Safety Board said it would continue to look at the pilot's experience and training in connection with the Feb. 12 crash that killed 50 people.

The NTSB said that while there was some ice present, "the airplane continued to respond as expected to flight control inputs throughout the accident flight."

The safety board added that "Preliminary airplane performance modeling and simulation efforts indicate that icing had a minimal impact on the stall speed of the airplane."

Fifty people died when the Continental Express commuter plane crashed a few miles short of the runway.

ABC News learned in mid-February that the pilot on the Buffalo flight may have put the plane into its deadly plunge.
