It also seems like this was not properly reported to safety agencies at the time, nor was it reported when that plane crashed in a subsequent flight.
Say what you will about Boeing, but this could have been avoided if the airline had better safety practices. Every pilot on that plane should have been trained on the new system. And the malfunction, if reported properly, should have caused that particular plane to be grounded for a mechanical inspection. Instead it flew again and hundreds of people died because they weren’t lucky enough to have one of the pilots who was trained properly.
- inferiorhuman 8y agoEvery pilot on that plane should have been trained on the new system. How is that supposed to work when Boeing didn't inform any of the airlines of this system?
- kayfox 8y agoIts in the type certificate and the maintenance manuals.
- inferiorhuman 8y agoNope. This has been the subject of a ton of teeth gnashing by the American pilot unions (the head of American Airlines' APA union has been among the most vocal critics of Boeing in this case). In fact if you look at the ANAC's (Brazil) version of the "OPERATIONAL EVALUATION REPORT" and compare it to the rest of the world you'll find only the Brazilian version references MCAS.
- twblalock 8y agoBoeing did inform them. Otherwise how would the third pilot have known what to do when he saved the plane?
- inferiorhuman 8y agoBoeing did inform them. Boeing did not inform any of the airlines of MCAS until after the Lion Air crash. Otherwise how would the third pilot have known what to do when he saved the plane? The deadheading pilot recognized a problem with something controlling the stabilizer and went off script. Edit: I love the downvotes from folks who haven't actually read any of the complaints from pilots. Since reading is too hard, have a video from the Washington Post: https://www.youtube.com/watch?v=ftZ6j8onS78 https://www.youtube.com/watch?v=ftZ6j8onS78
- twblalock 8y ago> The deadheading pilot recognized a problem with something controlling the stabilizer and went off script. It's not like he was pushing random buttons. He knew what the system was, he knew that it was likely to be the cause of the problem, and he knew how to disable it. He must have been informed about the system.
- inferiorhuman 8y agoHe knew what the system was How would he know something that was undisclosed? It's not conjecture here, no airlines and no pilots knew of the presence of MCAS before the Lion Air 610 crash.
- twblalock 8y agoThe article says that all of the pilots were supposed to know what to do in this situation: > The so-called dead-head pilot on the earlier flight from Bali to Jakarta told the crew to cut power to the motor driving the nose down, according to the people familiar, part of a checklist that all pilots are required to memorize. This guy didn't go off script. It seems like he was the only one of the three who knew the script.
- inferiorhuman 8y agoThis guy didn't go off script. It seems like he was the only one of the three who knew the script. The script says to stop if the trim adjustments stop when you counter with manual trim input. MCAS, by design, stops. You can see where MCAS stops trimming nose down on the preliminary Indonesian report (they graph both the fatal flight and the previous flight).
