The U.S. Federal Aviation Administration (FAA) told Boeing its planned 777X is not ready yet for a significant certification step and warned that it “realistically” will not certify the plane until mid- and late 2023.

The FAA in a May 13 letter to Boeing seen by Reuters quoted a number of problems in reject a request from the manufacturer of issue an availability for Type Inspection Authorization (TIA). “The plane is not ready yet for TIA, “wrote the FAA, declining approve “a phased TIA” of limited scope with a small number of certification flight test plans. “

The letter, which in previously had not been made public, cites numerous concerns about the lack of data and lack of a foreplay safety rating for the FAA a review.

“The FAA will not approve any aircraft unless it meets ours safety is standard certification, “the agency said in a statement on Sunday.

Boeing developed the widebody jet, a new version of his famous 777 aircraft, from 2013 et al one point should release it for airline company use in 2020.

A Boeing spokesperson said Boeing on Sunday that the company “remains completely concentrated on safety as ours highest priority in all 777X development. While we put the plane through a suit test program to prove her safety and reliability, we are working through a strict development process a ensure we all meet applicable requirements. “

The 777X will be the first main jet to be certified from software defects in two Boeing 737 MAX caused fatal crashes and solicited accusations of intimate relationships between the company and the FAA.

European regulators said in particular that they will subject the 777X to an extra check after the fatal the crashes required grounding for 20 months of the 737 MAX.

The MAX crashed in Indonesia and Ethiopia killed 346 people within five months in 2018 and 2019.

The letter mentions a number of problems that still need to face, including a “next major software update with the software to load of flight control . The FAA understands that there are many significant ones problem relationship items which will be addressed by that version of the software cargo, including the software fix for the uncontrolled step event it happened on 8 December 2020 “.

The agency added that “software upload dates are in continues to evolve and the FAA needs better visibility into the into causes of delays ».

It said that “after the launch not commanded event, the FAA has yet to see how Boeing fully implements all corrective actions identified by the root cause investigation.”

The agency said it wants Boeing to “implement such a robust process” escape not gonna happen in the future and this is not a system issue. “

The FAA said in its date of certification of the letter for the 777X “will actually be between mid to late 2023 (> 2 years from now).”

Boeing CEO Dave Calhoun said earlier this month that “we are still confident” that it will be certified in fourth quarter of 2023.

The letter was brought back in previously from the Seattle Times.
