RTX said it anticipates “a significant portion” of operators of the Airbus A32 0neo family aircraft, comprising of the A319neo, A320neo, and A321neo and its de rivatives, will have to remove the PW1100G engine quicker than anticipated for i nspection “within the next nine to twelve months”. This includes around “200 accelerated removals by mid-September of this year”, the company said. “The business is working to minimize operational impacts and support its custom ers. Management will provide additional detail on this matter during the earning s call,” RTX added. According to ch-aviation.com data, 3,246 Airbus A320neo family aircraft are powe red by the PW1100G engine with 68 different airlines globally. Out of those, 210 are stored, meaning that a total of 6.46% of the PW-powered A320neo family flee t is currently inactive. In comparison, there are 1,474 Airbus A321neo family aircraft powered by the CFM International LEAP 1-A, of which 74 are stored or in maintenance (5%), an analy sis of ch-aviation.com data showed. Throughout the year, Pratt & Whitney has struggled with its engine operations an d airlines have complained about operational reliability and slow turn-around ti mes (TAT) at engine shops. The affected engines included the PW1500G and PW1900G , powering the Airbus A220 and Embraer E2 aircraft, respectively, as well as the PW1100G. The engine family is also known as the Geared Turbofan (GTF). The most high-profile case related to P&W’s engine issues was when India-based Go First suspended operations, blaming Pratt & Whitney for “close to 50% of its A320neo fleet” being grounded by December 2022. 普惠的母公司RTX（前身为雷神技术公司）透露，为整个空中客车A320neo飞机系列提供动力 的大量发动机需要移除以进行检查。 RTX在2023年第二季度结果公告中表示：“普拉特和惠特尼已经确定，用於制造某些发动机零 件的粉末金属的罕见状况将需要加快车队检查。”并补充说，这个问题不会影响目前正在生 产的发动机。 RTX表示，预计空中客车A320neo系列飞机的“很大一部分”运营商将“在未来九到十二个月 内”进行检查，其中包括A319neo、A320neo和A321neo及其衍生产品，将不得不比预期更快地 拆除PW1100G发动机。 该公司表示，这包括大约“到今年9月中旬，加速迁移了200次”。 “该业务正在努力最大限度地减少运营影响，并支援其客户。 RTX补充说：“管理层将在收 益电话会议上提供有关此事的更多细节。” 根据ch-aviation.com的资料，3,246架空中客车A320neo系列飞机由PW1100G发动机提供动力 ，全球有68家不同的航空公司。 其中，储存了210个，这意味着目前共有6.46%的PW驱动的A 320neo家族舰队处於非活动状态。 相比之下，有1,474架由CFM International LEAP 1-A驱动的空中客车A321neo系列飞机，其 中74架被储存或维护（5%），对ch-aviation.com资料的分析显示。 全年，普惠公司一直在努力实现发动机运营，航空公司一直抱怨发动机店的运营可靠性和周 转时间（TAT）缓慢。 受影响的发动机包括PW1500G和PW1900G，分别为空中客车A220和巴西 航空工业E2飞机以及PW1100G提供动力。 发动机系列也被称为齿轮涡轮风扇（GTF）。 与P&W发动机问题相关的最引人注目的案件是，总部位於印度的Go First暂停运营，指责普惠 公司“其A320neo机队的近50%”在2022年12月前停飞。 [心得] 台湾虎航拼Q3创新板挂牌，预计2027年全机队A320neo机型将达15架 2023年7月20日 周四 下午3:08 台湾好像只有虎航中招了？ --
