The agency said it wants Boeing to “execute a durable procedure so comparable getaway will certainly not take place in the future as well as this is not a systemic problem.”
The FAA said in its letter certification date for the 777X “is genuinely mosting likely to be mid to late 2023 (>2 years from currently.”
