US government admits role in causing helicopter-plane collision that killed 67 in Washington

The U.S. government admitted Wednesday that the actions of an air traffic controller and Army helicopter pilot played a role in causing a collision last January between an airliner and a Black Hawk near the nation’s capital, killing 67 people.

It was the deadliest plane crash on American soil in more than two decades.

The official response to the first lawsuit filed by one of the victims’ families said that the government is liable in the crash partly because the air traffic controller violated visual separation procedures that night. Plus, the filing said, the Army helicopter pilots’ “failure to maintain vigilance so as to see and avoid” the airline jet makes the government liable.

But the filing suggested that others, including the pilots of the jet and the airlines, may also have played a role. The lawsuit also blamed American Airlines and its regional partner, PSA Airlines, for roles in the crash, but those airlines have filed motions to dismiss.

And the government denied that any air traffic controllers or officials at the Federal Aviation Administration or Army were negligent.
