Flight #: 400
Route: Pittsburgh - Newark

Summary: The aircraft yawed to the left and crashed shortly after takeoff after a fire warning occurred on the No.1 engine. The cause of the fire warning was a failed exhaust connector clamp in the left engine, which triggered an adjacent fire detecting unit. A windmilling left propeller, the extended landing gear, and the takeoff flaps produced sufficient drag to make the airplane lose altitude and strike the ground. An uncoordinated emergency action in a very short time available to the crew, which produced an aircraft configuration with insurmountable drag.
