The agency ordered an inspection of the 737 Max for cracks this summer, following reports of cracks in older models.
"After extensive safety reviews - including thousands of hours of test flights - the FAA is ready to approve this important aircraft for sale," the agency wrote in a statement.
Boeing 737 Max planes were involved in two fatal crashes in 2018 and 2019, killing a total of 346 people. The aircraft has been grounded several times.
