Air accident investigators faulted a flight-control feature on a Boeing Co. 737 MAX flown by Ethiopian Airlines that crashed in March, raising pressure on Boeing to fix the problem.
Ethiopian authorities, in a preliminary crash probe released Thursday, said the crew followed approved emergency procedures but couldn’t save the plane. They said Boeing BA, -1.54% should review the plane’s flight-control system and authorities should validate the changes before allowing the global MAX fleet, which was grounded after the crash, to return to service.
The stall-prevention feature, known as MCAS, has been the subject of intense scrutiny since another deadly crash of a 737 MAX in Indonesia last year. In early findings into that crash, investigators found a faulty sensor caused the system to mistakenly push down the nose of the jet—and that pilots weren’t able to take corrective action in time to avoid a crash. A similar sequence of events unfolded in the Ethiopian Airlines accident that killed all 157 people aboard.
The public findings Thursday of the Ethiopian preliminary report—which can change in subsequent examinations—puts the ball in Boeing’s court in terms of next steps fixing the system and defending the future safety of the jet. A Boeing spokesman said the company will review the report’s findings and comment further later. The company since last year has been working on a fix to improve how MCAS operates.

Investigators Believe 737 MAX Stall-Prevention Feature Activated in Ethiopian CrashOfficials investigating the fatal crash of a Boeing 737 MAX in Ethiopia have reached a preliminary conclusion that a suspect flight-control feature automatically activated before the plane nose-dived into the ground. in other news: Plane broke apart because it hit the ground. The AOA sensor is based on a potentiometer to provide the input signals.The power is provided by a non rechargeable Lithium battery .Could not the discharge and Life cycle issues of the battery be a cause that needs looking into? Which in turn may be the main cause ? “Automatically activated” ? Does it mean no faulty sensor was involved ? And why the AoA sensors are so prone to faults ?

Would have been a shocker if that wasn’t the case. Incredibly sad that these ppl died so unnecessarily. Completely preventable. Hearts and prayers with the victims and their families. So the plane has 2 AoA probes, but only uses input from one at a time into it's Air Data Computer. So if the one it's using malfunctions, the plane thinks it's stalling and pitches nose down. How about use both AoA probes, for redundancy/reliability?

Ethiopian Airlines pilots said to have followed protocol before 737 Max crashPilots on the Ethiopian Airlines flight that crashed last month followed protocol set by planemaker Boeing Co. to manually disable an automated anti-stall system as they tried to save the Boeing Co. 737 Max jet, a person familiar with the situation said. The Pilots are not using a super high speed anti-stall system. They are using the rotor at a slightly higher speed than the main rotor. You can't do this at a gimbal or high speed.

Sensor damaged by a foreign object on Ethiopian Airlines 737 MAX triggered fatal crash: SourcesJUST IN: Ethiopian Airlines Boeing 737 MAX suffered a damaged sensor upon takeoff from a bird or foreign object, triggering fatal crash, two aviation sources familiar with the investigation tell ABC News. Sounds like this crash and the other were unrelated except they were the same kind of jet Still a massive mistake making any flight critical system single device only, especially one with control over the rudders for the anti-stall mechanism. Most flight systems have double if not triple redundancy. ‘Beyond Sketchy’: Facebook Demands Users’ Email Passwords
