The 737 MAX ban was lifted Wednesday by the Federal Aviation Administration.
FAA Administrator Steven Dickson said he was "100% confident" in the safety of the aircraft after rescinding a 20-month old order that allows the plane to resume commercial flights. The 737 MAX was grounded in March 2019 following two crashes that killed 346 people. The crashes ultimately were linked to the jet's navigation system.
Reuters reported that the FAA will detail software upgrades and training changes the planemaker must make in order for it to resume commercial flights.
The FAA also said Boeing (BA) - Get Boeing Company Report will not be allowed to sign off on the airworthiness of about 450 already-built 737 MAXs. The agency, therefore, plans in-person, individual inspections that could take a year or more to complete, prolonging the jets’ delivery, Reuters noted.
