The Federal Aviation Administration (FAA) said on Wednesday it had approved the design for the Boeing 737-8200, part of the Boeing 737 MAX series, a necessary step before the U.S. planemaker can begin delivering the airplanes to Ryanair. The FAA said the 737-8200 incorporates all of the design improvements that were part the 20-month review of the 737 MAX that led to the ungrounding of the MAX in November, more than a year after two fatal crashes killed 346 people. Ryanair first ordered the 737-8200 plane, which seats 197 passengers, in 2014. The European Union Aviation Safety Agency still must approve the aircraft, a move that could come soon after the FAA approval. Boeing said Wednesday it would “continue to work with global regulators to safely return the 737-8 and -9 to service. Our teams are also focused on ensuring future members of the 737 family meet all regulatory requirements.”
