If I recall it was alleged that it was a miswiring to the engine fire indicators and not a computer issue. However, that too was debunked.


In any case, it was still pilot error because there are other engine indicators that can tell you if an engine is working or not. You have N1/N2 indicators, turbine temperatures, fuel pressure, oil pressure, vibration indicators.....and you can always ask the flight attendant to look thru the window to see where is the fire.

They got fixated on information based on their previous experiences flying the earlier B737-200 ( smell in the cabin ).

If the pilots looked at the big picture before shutting down the wrong engine, they would have been able to make a safe landing. Training is crucial to that end and so is cockpit resource management.

Saying all that, pilots need good emergency situation training especially in modern jets. If you don't understand what is going on, you can't stabilize the situation. In the case of the Max, Boeing did a piss poor job in training their customer pilots saying it was just like their old B737. ( here is a slide show on a tablet and in one hour you are qualified kind of a thing ).

and then, there is airmanship. Some pilots do not know how to properly manage or recover the aircraft during upset ( turbulence or icing conditions ).


and finally, the aircraft makers need to make the cockpits and system as straight forward and easy to understand as possible. Introduce many failure scenarious before the aircraft is certified.

We will continue to learn until robots take over the controls of the plane. I think that is inevitable in less than 100 years from nw. ( my opinion ).

No computers involved.

The Co-pilot misdiagnosed it. Initially saying Left engine failure but then changing his statement to right engine with the pilot agreeing due to experience on earlier versions of the 737.

Their mistake was covered up by the fact that as the Co-pilot shut down the right engine the captain disengaged autopilot and auto-throttle which caused the left throttle to close reducing the vibration and making it appear that the right engine was the problem. Confirmation bias mislead the crew to think they had got it right.

Nothing to do with computers. more human factors from previous experience and confirmation bias.

Still a bit off-topic - those interested in accidents may be interested in this post, as I have posted the actual SA Civil Aviation Authority Investigation Report. One mess after another!
