Ethiopian Air pilots said to follow protocol on 737 Max flight

Ethiopian Air pilots said to follow protocol on 737 Max flight

MCAS, which is programmed to push down a plane's nose to help prevent aerodynamic stalls in some situations, is a focus of concern by regulators and lawmakers after 346 people died in crashes of Boeing's newest version of the 737 flown by Ethiopian and Lion Air less than five months apart.

The pilots then cranked a manual wheel in an attempt to stabilize the plane, the report said, but they eventually chose to restore power to the usual electric trim on their control yokes, likely because the manual attempt didn't achieve the desired results.

A preliminary Ethiopian report into the disaster is due to be published within days and may include evidence the software system kicked in as many as four times before the 737 MAX dived into the ground, two people with knowledge of the matter said. New reports indicate the crew of the Ethiopian Airlines flight that crashed shortly after takeoff reportedly did follow Boeing emergency procedures to turn off an anti-stall system, but may have turned it back on in an effort to regain control of the plane.

The crash killed all 157 people on board and led to a global grounding of 737 MAX jets.

The facility, owned by XTRA Aerospace, did maintenance on the Boeing 737 Max before the fatal crash, documents prepared for the country's parliament show.

Ethiopian investigators were not available for comment. But the pilots failed to regain control of the system, and the MCAS was reactivated again-triggering yet another automated correction of the aircraft's stabilizers that would have pushed the nose of the plane down.

Air Canada said on Tuesday it would delay the launch of certain seasonal flights this spring, as the carrier wrestles with the challenge of servicing routes previously flown by its grounded Boeing 737 MAX aircraft.

Speaking to journalists in Nairobi, the lawyers said they will file the case in the United States seeking compensation for the families over the March 10 plane crash.

The report does not link the fix shop to the Ethiopian Airlines' jet, the second such plane to crash.

Boeing is upgrading the MCAS software and training while stressing that existing cockpit procedures enable safe flight.

The reports by The Wall Street Journal and Reuters, based on interviews with unnamed sources who have been briefed on the post-crash investigation's preliminary findings, raise deeper questions about the safety of the flight control system, known as the Maneuvering Characteristics Augmentation System, or MCAS.
