Probable cause
Total loss of power in the left engine from ice ingestion; and failure of the left-engine auto-relight system caused by an open fuse in the Digital Electronic Control Unit (DECU), which prevented an automatic relight of the left engine. Factors relating to the incident were: inadequate design of the engine air inlet anti-ice system, which allowed ice/slush accumulation; inadequate action by the FAA to ensure compliance with certification requirements regarding inlet ice accumulation; and an inadequate procedure in the flight manual concerning use of the engine synchrophaser during single-engine operation.
