With a crucial summit for the Boeing Co. 737 Max looming this week, regulators are downplaying the threat of a rupture to a decades-old working relationship between U.S. and European aviation authorities. On the eve of a gathering of about 50 airworthiness experts in Montreal, the top European regulator, Patrick Ky, suggested that the Max could return to the air in the U.S. and Europe at almost the same time.
And officials privately have been discussing whether a critical disagreement over the jet’s architecture could be resolved after it resumes commercial flight, according to people familiar with the talks.
