THE ICE CRYSTAL ICING CONUNDRUM

摘要

In July 2013 a 747-800 freighter aircraft operated by Russian company AirBridge Cargo was en-route from Moscow to Hong Kong, cruising at FL410 when the crew experienced simultaneous surges to both left-hand engines. The number two engine flamed out but subsequently relit, however, on landing in Hong Kong both left-hand engines (along with one right-hand engine) were found to have suffered unacceptable high-pressure compressor blade damage.
