The US Federal Aviation Administration (FAA) has announced that the 777X is not yet ready to receive certification and has warned Boeing that it will not certify the aircraft until mid-2023.
In a letter to Boeing, the FAA cited a number of issues in rejecting the manufacturer's request to issue a TIA inspection clearance. "The aircraft is not yet ready for the TIA", wrote the FAA, refusing to approve "A limited-stage step-by-step TIA with a small number of certification flight test plans". The letter, which had not been made public before, mentions many concerns about the lack of data and the lack of a preliminary safety assessment for the FAA to review.
"FAA will not approve any aircraft unless it meets our safety and certification standards.", the agency said in a statement on Sunday. Boeing has been developing the widebody jet, a new version of the 777 aircraft, starting in 2013 and is expected to be launched for airline use in 2021.
The FAA will not approve any aircraft unless it meets safety and certification standards.
On 30 April the second Boeing 777X successfully operated the first flight. The captain Ted Grady, pilot of the 777X project, and captain Van Chaney, 777 / 777X chief pilot, flew over Washington for 2 hours and 58 minutes.
matriculate WH002, this is the second in a fleet of four 777X aircraft, which are dedicated to ground and in-flight testing. The Boeing 777X program is on track. The test plan for the 777X presents a comprehensive set of ground and air conditions to demonstrate the safety and reliability of the aircraft.
European regulators have said they will subject the 777X to additional scrutiny following problems with 737 MAX aircraft, which were detained on the ground for almost 2 years. After a long hiatus, the Boeing 737 MAX aircraft fleet is back in the air. The FAA (Federal Aviation Administration) has approved resumption of flights with 737 MAX aircraft, in November 2020, for airlines under FAA jurisdiction. Subsequently, other territorial authorities also agreed to resume flights with 737 MAX aircraft in Europe, the United Kingdom, Canada, Brazil and the United Arab Emirates. However, this is not the case in Asia, where the 737 MAX aircraft fleet remains on the ground.
