American Airlines Flight 182, a Douglas DC-10-10 (N124AA) and Trans World Airlines flight 37, a Lockheed L-1011 TriStar (N11002), almost collided head-on at 35000 feet near Carleton, Michigan, USA, within positive control airspace, and while under the control of the Cleveland
Air Route Traffic Control Center. Both aircraft were operating in instrument meteorological conditions,
As a result of the evasive maneuver executed by the captain of the DC-10, 3 aircraft occupants were injured seriously and 21 were injured slightly. The cabin's interior was damaged extensively. None of the occupants of the L-1011 was injured.

The National Transportation Safety Board determines that the probable cause of this near-collision was the failure of the radar controller to apply prescribed separation criteria when he first became aware of a potential traffic conflict which necessitated an abrupt collision avoidance maneuver.
He also allowed secondary duties to interfere with the timely detection of the impending traffic conflict when it was displayed clearly on his radarscope. Contributing to the accident was an incomplete sector briefing during the change of controller personnel--about 1 minute before the accident.
