Southwest and FAA officials never knew Boeing turned off a safety feature on its 737 Max jets, and dismissed ideas about grounding them

Southwest Airlines and the Federal Aviation Administration (FAA) officials who monitor the carrier were unaware that a standard safety feature, designed to warn pilots about malfunctioning sensors, on Boeing 737 Max jets was turned off when Southwest began flying the model in 2017, reported Andy Pastzor of the Wall Street Journal.
In earlier 737 models, the safety feature alerted pilots when a sensor called the "angle-of-attack vane" incorrectly conveyed the pitch of the plane's nose, according to Pastzor. In the Max, it functions as such while also signaling when the Maneuvering Characteristics Augmentation System (MCAS) a new automated system linked to both October's Lion Air crash and March's Ethiopian Airlines crash could misfire; but these alerts were only enabled if carriers purchased additional safety features, Pastzor wrote.
Like other airlines flying the Max, Southwest didn't learn about the change until the aftermath of the Lion Air crash, Pastzor reported.
According to WSJ's investigation, which reviewed documents, the carrier then asked Boeing to reactivate the alerts on its Max fleet, causing FAA inspectors to contemplate grounding the Max fleet until it was determined whether or not pilots needed additional training but the idea was quickly dropped.
Once the feature was reactivated, some FAA officials again considered grounding Southwest's 737 Max fleet to determine whether pilots needed new training and again, the discussions, which happened via email, were dismissed after a few days, Pastkor reporter.
