Boeing doesn’t expect MAX 10 to gain FAA approval before summer 2023

Boeing Co does not anticipate winning approval for the 737 MAX 10 before next summer, according to a Federal Aviation Administration (FAA) letter sent on October 3 that intensifies concerns about the company's timeline for deliveries, Report informs referring to Reuters.

Boeing faces a December deadline to win regulatory approval for the MAX 10, which is slightly larger than current 737 MAXs in service, as well as for a smaller variant, the MAX 7.

Unless it gains an extension from Congress, Boeing must meet new modern cockpit-alerting requirements that could significantly delay the planes' entry into service.

"With regard to the 737-10, Boeing's current project plan timeline has the 737-10 receiving an amended type certificate no sooner than summer 2023," two sources quoted acting FAA Administrator Billy Nolen as saying in a letter to Senator Roger Wicker, the top Republican on the Senate Commerce Committee.

Boeing has recently booked major MAX 10 orders from Delta Air Lines, Canada's WestJet Group and other carriers.
