The new Boeing 777X is not yet ready for certification

The US Federal Aviation Administration (FAA) has informed aircraft manufacturer Boeing that the new 777X is not ready to go through the certification process and the office will not be able to issue a certificate before mid-2023. In a letter dated May 13, a copy of which was obtained by Reuters, the FAA named a number of issues. This is the reason why the FAA refused to issue a TIA type certificate. "The plane is not yet ready to obtain a TIA," Reuters was quoted as saying. It lists a number of data deficiencies and preliminary safety tests that the FAA needs. "The FAA will not approve any aircraft until it meets our safety and certification standards," the office said in a statement on Sunday. Boeing has been developing a new version of the popular 777 since 2013, and airlines were originally expected to be able to buy it in 2020. The new 777X is set to become the first approved civilian transport aircraft since two Boeing 737 MAX accidents caused by software bugs that killed 346 people in Indonesia and Ethiopia in 2018 and 2019. They have resulted in a deterioration in relations between Boeing and the FAA and a 20-month "grounding" of 737 MAX aircraft. European regulators also intend to thoroughly review the 777X. The letter also lists issues that Boeing must address, including updates to flight control software and other software vulnerabilities that could compromise aircraft safety. The FAA is asking Boeing to put in place control processes to prevent damage to the aircraft's control systems.
