Probable cause
High-altitude ice crystals that had accreted on the compressor vanes and were ingested into the engine high pressure compressor when the pilots retarded the power levers causing compressor surges and the flameouts of both engines. Contributing factors were the lack of training on the hazards of high-altitude ice crystals to gas turbine engines and guidance to the pilots to activate the engine anti-ice system in conditions where high-altitude ice crystals may exist.
