EU Signals Caution on Max Return with No Rubber Stamp of FAA (excerpt)

European regulators assessing changes to Boeing Co.’s grounded 737 Max will scrutinize the jet’s entire flight-control system before a return to the skies can be approved.

The review by the European Union Aviation Safety Agency will include the plane’s displays, alerts and air-data systems, as well as the aircraft’s autopilot function, EASA Director Patrick Ky wrote in a letter dated May 27 and seen by Bloomberg. The update was sent to members of the EU Parliament’s Transport Committee in response to questions they raised last month about aviation oversight. The Max was grounded earlier this year following two fatal crashes in Indonesia and Ethiopia that killed almost 350 people.

For the Max to return to service, Boeing will have to show that the probability of a “catastrophic failure” is less than one-in-a-billion flight hours -- the standard in the industry, according to Ky.

When an action by a crew member is required to meet those odds, EASA will re-evaluate “both the man-machine interface and the training” procedures for pilots, he said. In each of the Max accidents, pilots tried unsuccessfully to pull the plane out of a dive triggered by an erroneous sensor.

EASA didn’t immediately respond to requests for comment.

The agency’s letter shows the extent of the European regulator’s plans for independently ensuring the Max’s safety, which could add to the time the plane remains grounded in the region.

Some members of the EU parliament’s transport committee have raised concerns that the U.S. Federal Aviation Administration delegated part of the aircraft certification process to Boeing itself, and queried whether there were safeguards between EASA and European manufacturers. (end of excerpt)
