At 1525 c.d.t., August 6, 1976, N9446Z crashed while attempting an emergency landing on runway 4L at Midway Airport, Chicago, Illinois. The left engine failed during climbout from Midway Airport, which precipitated an uncontrollable engine fire. The aircraft crashed into a residential area about 3/4 mile west of the airport. The aircraft was destroyed, and its two crewmembers killed. One person on the ground was killed, and one person was injured seriously. Two houses, two garages, three automobiles, and a boat were destroyed. The National Transportation Safety Board determines that the probable cause of the accident was the deterioration of the cockpit environment, due to smoke to the extent that the crew could not function effectively in controlling the aircraft under emergency conditions. The smoke and fire, originating from a massive failure in the power section of the left engine, propagated into the bomb bay area and then into the cockpit. The inspection system utilized was not effective in detecting the impending engine failure.
