Engines on some Airbus jets with Pratt & Whitney engines will need to be 除去するd and 検査／視察するd
DALLAS (AP) - A large number of Airbus 乗客 jets will need to have their engines 除去するd and 検査／視察するd in the coming months after engine 製造者 Pratt & Whitney discovered a problem that could 原因（となる） parts to wear out more quickly, 潜在的に 追加するing to 強調する／ストレス on 航空機によるs during the 残りの人，物 of a hectic summer travel season.
株 of Pratt & Whitney parent RTX Corp. fell 11% Tuesday afternoon after the company 公表する／暴露するd the 問題／発行する.
RTX said that a "rare 条件" in 砕く metal used to 製造（する） 確かな parts made between late 2015 and 中央の-2021 will 要求する 速度(を上げる）d-up (n)艦隊／(a)素早い 査察s. The engine 伴う／関わるd is most often used to 力／強力にする the Airbus A320neo, a midsize jet popular for short and medium-distance flights.
The company said it 推定する／予想するs that about 200 of Pratt PW1100 engines will need to be pulled off and 検査／視察するd by 中央の-September, and another 1,000 engines will need 査察s in the next nine to 12 months.

On a call with 分析家s, RTX 長，指導者 Operating Officer Christopher Calio said that the problem does not 影響する／感情 現在の 生産／産物, and Pratt will continue to produce new engines and spare parts, but the life of parts made between late 2015 and 中央の-2021 could be reduc ed.
Pratt had planned to schedule "高めるd 査察s" during normal 維持／整備 stops, but based on 最近の 発見s, it decided that the 査察s - 焦点（を合わせる）d on high-圧力 turbine disks - needed to be 速度(を上げる）d up, Calio said. He said the company is developing 計画（する）s to 行為／行う the 査察s as quickly as possible.
