Original title: Boeing was warned by the U.S. Aviation Administration that 777X will not be certified before mid-2023
China-Singapore Jingwei Client, June 28. According to the Wall Street Journal’s Chinese website on the 28th, the American Aviation Administration (FAA) has informed Boeing that its new version of the 777X long-range airliner is not yet certified, and it is likely to wait until the end of 2023.
It is reported that last Sunday, the “Seattle Times” first reported that the FAA sent a letter to Boeing on May 13 to warn that it may need to conduct more test flights on the 777X aircraft. In reality, there is a key issue. Safety certification will take more than two years. Since then, Reuters and Bloomberg news reports have confirmed this news.
The report pointed out that the above letter mentioned some concerns, including problems with the 777X flight control software. In a previous test flight in December 2020, the software suddenly tilted the aircraft without the pilot inputting instructions.
The FAA also warned that the agency will not certify the 777X in advance until the middle of 2023, and certification may not be possible until the middle and late stages.
The 777X is the first large aircraft that Boeing has applied for certification after two fatal crashes on the 737MAX. Up to now, the delivery time of this model has been delayed twice, from 2020 to 2021, and then to 2023 now.
This will also delay the commercial debut of the 777X until 2024, about four years later than the original plan. (China-Singapore Jingwei APP)
