The airplane was destroyed at about 1550 Eastern time when it impacted a residential area following a loss of engine power after takeoff. Visual conditions prevailed. The two Airline Transport pilots and the passenger reported serious injuries; two persons on the ground reported minor injuries. The pilot later reported, as the landing gear was being retracted, he felt a slight hesitation and mild backfire from the left engine. He saw that the engines cowling was covered with oil. The crew attempted to secure the left engine, but its propeller never went into the feathered position. At that time, the decision was made to put the airplane down on a road.
