Boeing has advised GEnx engine operators that it is revising the 787’s and the 747-8’s flight manuals to prohibit flight within 50 nm of thunderstorms that may contain ice crystals. Following Boeing’s recommendation, Japan Airlines immediately announced it would switch aircraft on two routes. From April to November, GEnx-powered aircraft suffered six engine-icing events, according to a GE statement. All aircraft landed at their planned destinations, said the engine maker, and none of the incidents involved in-flight shutdowns–only temporary thrust losses.
GE expects the U.S. Federal Aviation Administration to issue an airworthiness directive (AD) detailing inspection intervals for GEnx engines “within a day or two,” following the latest contained failure of a GEnx-2B in Shanghai, China.
Managing aircraft programs is a complex process that should not be underestimated. This is one of the clearest messages to have emerged in recent years and is evidenced when one considers the 787 supplier issues, A380 wiring problems and A400M delays. It costs the industry vast sums of time and money.
The Teamcenter product lifecycle management suite being demonstrated here by Plano, Texas-headquartered Siemens PLM Software (Hall 3, Stand C6) has played a crucial role in the Sukhoi SSJ-100 Superjet’s progress from concept to its recent first flight, said Tim Nichols, the company’s managing director of aerospace global marketing.
