Boeing 737 Max’s Europe flight test still on hold as FAA moves ahead

Travel restrictions brought on by the Covid-19 pandemic continue to slow the re-certification process for Boeing Co.’s 737 Max in Europe, even after U.S. aviation regulators moved a step closer to allowing the grounded jet to fly again.

The European Union Aviation Safety Agency said it’s still working with Boeing and the U.S. Federal Aviation Administration to find a solution that would allow it to conduct its own test flights for the jet. None of the flights, a prerequisite for the 737 Max’s return to service in Europe, have been scheduled.

“Good progress has been made but there is still some work which Boeing needs to complete,” EASA said by email, without elaborating. “In the light of this position, and in common with the FAA, we cannot yet predict a firm schedule for the return to service and the ungrounding of the aircraft in Europe.”

Public Comment

On Monday, the FAA asked for public comment on proposed changes it will require for recertification of the 737 Max, which was grounded after two crashes killed 341 people. Boeing has said it expects to resume deliveries of the narrow-body plane this year.

The FAA’s action shows that, after 16 months and numerous probes and congressional hearings, aviation regulators are satisfied that the fixes will allow the plane to safely resume service. Flight tests of the redesigned systems by the FAA were completed July 2.

In addition to changes specific to the system implicated in the accidents, the FAA proposal would mandate broad computer changes to improve reliability, add a warning light that was inoperative in the two crashes and require the rerouting of electrical wires that don’t meet safety rules.

“EASA has been working closely with the FAA and Boeing throughout with the common aim of returning the 737 Max to service as soon as possible, but only once we are convinced it is safe,” the European agency said.
