Boeing will need to complete more 777-9 analysis and assuage regulatory concerns, including those related to design changes, prior to the Federal Aviation Administration agreeing the jet is on track to meet certification requirements.
That is according to a recently-released letter in which the FAA outlines concerns and says it is unlikely to issue the 777-9’s amended type certificate until mid- to late-2023.
The given timeline does not mean a fresh delay for the 777-9 because, in January, Boeing pushed back its first planned 777-9 delivery until late 2023.
The letter, dated 13 May, highlights changes Boeing is making to the 777-9 and mentions lack of clarity about progress toward certification in Europe. It says the FAA needs more information – including about a major software architecture called the “Common Core System” (CCS) – before considering the 777-9 to be on track to certification.
