Boeing Co (NYSE: BA ) does not expect approval for the 737 Max 10 until next summer, according to a report that cited a letter from the Federal Aviation Administration citing growing concerns about the airline’s delivery times. Boeing has December to seek regulatory approval for the Max 10. Reuters reported that if Boeing doesn’t get an extension from Congress, it will have to meet new cockpit alarm requirements. „Regarding the 737-10, Boeing’s current project timing calls for the 737-10 to be recertified no earlier than summer 2023.” The report mentions FAA acting director Billy Nolen, as noted in a letter to Sen. Roger Wicker, the top Republican on the Senate Commerce Committee. Last week, Boeing agreed to pay $200 million to settle SEC allegations of a lack of disclosure following the 2018 and 2019 plane crashes. Wicker has proposed extending Boeing’s deadline for approval of the two new variants to September 202 and hopes to include the proposal in the annual bill. According to the report, it is unclear whether Congress would be prepared to pass the proposal. Nolen’s letter stated that the FAA cannot set a deadline for the MAX 7 or MAX 10 certificate.
