[媒體名稱] [新聞日期] aerotime 7/25 [網址] https://www.aerotime.aero/articles/pw-new-a320neo-family-issue/amp [內文] Pratt & Whitney’s parent company, RTX (formerly Raytheon Technologies), has rev ealed that a significant number of engines powering the entire Airbus A320neo ai rcraft family will need to be removed for inspection. “Pratt & Whitney has determined that a rare condition in powder metal used to m anufacture certain engine parts will require accelerated fleet inspection,” RTX said in its Q2 2023 results announcement, adding that the issue does not affect engines currently in production. 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（前身為雷神技術公司）透露，為整個空中客車A320neo飛機系列提供動力 的大量發動機需要移除以進行檢查。 RTX在2023年第二季度結果公告中表示：“普拉特和惠特尼已經確定，用於製造某些發動機零 件的粉末金屬的罕見狀況將需要加快車隊檢查。”並補充說，這個問題不會影響目前正在生 產的發動機。 RTX表示，預計空中客車A320neo系列飛機的“很大一部分”運營商將“在未來九到十二個月 內”進行檢查，其中包括A319neo、A320neo和A321neo及其衍生產品，將不得不比預期更快地 拆除PW1100G發動機。 該公司表示，這包括大約“到今年9月中旬，加速遷移了200次”。 “該業務正在努力最大限度地減少運營影響，並支援其客戶。 RTX補充說：“管理層將在收 益電話會議上提供有關此事的更多細節。” 根據ch-aviation.com的資料，3,246架空中客車A320neo系列飛機由PW1100G發動機提供動力 ，全球有68家不同的航空公司。 其中，儲存了210個，這意味著目前共有6.46%的PW驅動的A 320neo家族艦隊處於非活動狀態。 相比之下，有1,474架由CFM International LEAP 1-A驅動的空中客車A321neo系列飛機，其 中74架被儲存或維護（5%），對ch-aviation.com資料的分析顯示。 全年，普惠公司一直在努力實現發動機運營，航空公司一直抱怨發動機店的運營可靠性和週 轉時間（TAT）緩慢。 受影響的發動機包括PW1500G和PW1900G，分別為空中客車A220和巴西 航空工業E2飛機以及PW1100G提供動力。 發動機系列也被稱為齒輪渦輪風扇（GTF）。 與P&W發動機問題相關的最引人注目的案件是，總部位於印度的Go First暫停運營，指責普惠 公司“其A320neo機隊的近50%”在2022年12月前停飛。 [心得] 台灣虎航拼Q3創新板掛牌，預計2027年全機隊A320neo機型將達15架 2023年7月20日 週四 下午3:08 台灣好像只有虎航中招了？ --
