Boeing encountered yet another unexpected setback in returning the company's most popular model aircraft to service this week after it found a bug during software testing for the plane's new software update.

Boeing notifies FAA of a software glitch in the flight-control computer in the 737 MAX 8, pushing pack the planes return to service even further

As Boeing struggles to return the company's best-selling aircraft to service, it has identified another, unrelated software bug in the grounded plane's flight control computer that subsequently reported to the FAA, reportedly delaying the plane's upcoming certification flight.


In a new report in the Wall Street Journal, Boeing engineers were testing the flight control computer in a grounded 737 MAX 8 when they identified an anomaly in its first-stage software system monitor. Essentially, this system function monitors the start-up of other necessary systems to ensure that everything loads as it should.

The system failure occurred when the engineers introduced changes to the system to test its navigation. Fortunately, the specific location where the failure occurred meant that the plane could not be airborne and encounter this bug at the same time, so there isn't concern that poses a crash risk.

The bad news is that it does completely crashed the plane's computer system, which then has to go through the start-up process all over again.

This latest bug comes at a bad time for Boeing as they prepare for the updated 737 MAX 8 to undergo a certification flight in the coming weeks or months. It needs to pass this certification flight if Boeing ever hopes to get past its 737 MAX 8 crisis.
