Europe’s top aviation regulator said he’s satisfied that changes to Boeing Co’s 737 Max have made the plane safe enough to return to the region’s skies before 2020 is out, even as a further upgrade his agency demanded won’t be ready for up to two years.
After test flights conducted in September, EASA is performing final document reviews ahead of a draft airworthiness directive it expects to issue next month, said Patrick Ky, executive director of the European Union Aviation Safety Agency.
That will be followed by four weeks of public comment, while the development of a so-called synthetic sensor to add redundancy will take 20 to 24 months, he said. The software-based solution will be required on the larger Max 10 variant before its debut targeted for 2022, and retrofitted onto other versions.
“Our analysis is showing that this is safe, and the level of safety reached is high enough for us,” Ky said in an interview. “What we discussed with Boeing is the fact that with the third sensor, we could reach even higher safety levels.”
The comments mark the firmest endorsement yet from a major regulator of Boeing’s goal to return its beleaguered workhorse to service by year-end, following numerous delays and setbacks. The Max, the latest version of the venerable 737 narrow-body, was grounded in March 2019 in the wake of two accidents that took 346 lives, setting into motion a crisis that’s cost Boeing billions of dollars and then-CEO Dennis Muilenburg his job.
While the Federal Aviation Administration (FAA), Boeing’s main certification body, is further along in its review, it has held back from making predictions about the timing. FAA chief Steve Dickson flew the Max late last month and said the plane’s controls felt “very comfortable,” but the review process wasn’t complete.
The FAA must act before EASA and other agencies around the world can lift the grounding, under international law. Boeing hasn’t submitted its final package of documentation including software audits and safety assessments, said a person familiar with the process who wasn’t permitted to speak publicly. The submissions are expected soon.
