This AD results from multiple reports of high-altitude, dual-engine flameout on airplanes operating in certain meteorological conditions. We are issuing this AD to advise the flightcrew that the buildup of ice on certain internal areas of the engine could result in a dual-engine flameout and what action they must take to avoid this hazard.
