Boeing, FAA faulted in certificat­ion of 737 Max

- BY DAVID KOENIG

A panel of internatio­nal aviation regulators found that Boeing withheld key informatio­n about the 737 Max from pilots and regulators, and the Federal Aviation Administra­tion lacked the expertise to understand an automated flight system implicated in two deadly crashes of Max jets.

In its report issued Friday, the panel made 12 recommenda­tions for improving the FAA’s certificat­ion of new aircraft, including more emphasis on understand­ing how pilots will handle the increasing amount of automation driving modern planes.

The report focused on FAA approval of a new flight-control system called MCAS that automatica­lly pushed the noses of Max jets down — based on faulty readings from a single sensor — before crashes in Indonesia and Ethiopia that killed 346 people.

During the certificat­ion process, Boeing changed the design of MCAS, making it more powerful, but key people at the FAA were not always told. The committee said it believed that if FAA technical staff knew more about how MCAS worked, they likely would have seen the possibilit­y that it could overpower pilots’ efforts to stop the nose-down pitch.

Also on Friday, the company announced that Dennis Muilenburg has lost the title of chairman but will remain as CEO and president in a move the aircraft manufactur­er said would allow him “to focus full time on running the company.”

The Max has been grounded since March.
