Swearingen SA227 Metro III

The aircraft departed during low ceiling, low visibility, and night conditions. Shortly after takeoff the aircraft impacted a reservoir. Analysis of radar data indicated the aircraft was in a 45° descending turn. Examination of the aircraft trim system showed that the aircraft was trimmed for level flight. There was no voice or flight data recorder on board. A review of ATC communications indicated that the captain was communicating with ATC allowing the first officer to accomplish the flying duties. Examination of the wreckage revealed no indications of powerplant or system failures. However, there was evidence that the sas warning light was illuminated, the sas switch was in the off position, and no sas system malfunction could be found. Witnesses stated that before the flight the captain had complained of illness but he decided to report for duty. Company records showed instances of substandard performance by the first officer. The investigation found company oversight of training, operations, and inadequate faa supervision. All 12 occupants were killed.

The aircraft had descended through a cloud layer enroute for the scheduled landing at IAD and according to the crew had picked up some trace rime ice on its wing surfaces. Although pitot and sas (stall avoidance system) heat were used the captain elected not to use engine inlet anti-ice. Just inside the outer marker the left engine lost power followed shortly by the right engine. The captain was able to set the aircraft down in an open field where the gear collapsed during the landing roll. The engines were successfully run-up at the Garrett facility. The flight manual contains a warning and a note stating that engine heat and continuous ignition must be used after leaving icing conditions until the pilot is confident that any significant residual ice will not be ingested into the engines. Ice was found lying beneath the right wing which matched the curvature of the leading edge of the wing. A round conical shaped piece of ice was found along the wreckage path which matched the nose of the propeller spinner.
