What contributed to the Lion Air flight 610 accident is not the presence of alpha vanes alone, nor the fact one was installed incorrectly. If they fed just stall warning, it would be relatively easy to recognize it as spurious. The main factors were that the Maneuvering Characteristics Augmentation System (MCAS)—kind of unusually implemented stick pusher—does not check for mismatch between the sensors, and that maintenance instructions don't include the alpha vanes as possible cause for the issues from preceding flight. | |
