Boeing uncovers flawed 737 MAX flight simulators

Boeing has newly found that its flight simulators used to train pilots failed to precisely imitate the conditions that resulted in its MCAS anti-stall system malfunctioning, the New York Times reports.

Why it matters: Airlines are seeking ways to ensure their pilots are able to handle any malfunctions on the 737 MAX once they resume service, Axios' Andrew Freedman writes. If the simulators fail to replicate what went wrong in the two fatal crashes, then pilots won’t be able to realistically experience how to properly respond, even if the FAA does not require the use of simulators.

After Lion Air crash, Boeing rebuffed pilots' call for software fix or 737 MAX grounding

American Airlines' pilots union pressed Boeing executives to fix the planes' anti-stall software or ground the 737 MAX after the fatal Lion Air crash in November 2018, but corporate leadership refused to listen — reports the New York Times.

Our thought bubble from Axios' Andrew Freedman: It's unusual to have pilots unions ask an aircraft manufacturer to correct a safety feature or possibly ground an aircraft in the first place. For them to be rebuffed on such a request is even more remarkable. This indicates a breakdown in trust between Boeing and the pilots flying its 737 MAX jets after the crash of the Lion Air plane in October and before the Ethiopian Airlines accident in March. Lawmakers and federal investigators are looking into what Boeing told pilots unions about the plane's anti-stall system known as MCAS, which is suspected to have contributed to both crashes.
