Southwest Airlines has recently canceled Boeing 737 Max flights until at least November. The decision was made after the Federal Aviation Administration recently discovered a new flaw in the plane’s flight software.
Boeing CEO Dennis Muilenberg said in a tweet Thursday that “the plane’s grounding, which was ordered by regulators around the world in March, is presenting significant challenges for our customers, company and supply chain.”
On Thursday Boeing also announced that it will take a $4.9 billion hit in the second quarter alone from the grounding of the flight, and that it doesn’t expect the plane to return to flight until the fourth quarter of the year. The company has set up a $100 million fund for the families and communities of the victims.
The deadly crashes were mainly caused by software that was supposed to prevent the newer 737 Max planes from stalling in certain situations. That software, known as Maneuvering Characteristics Augmentation System, or MCAS, made calculations based on readings from a single external sensor on the plane, and also had no way to know if that sensor was damaged.
This was the case in both of the crashes. What made matters worse was that pilots didn’t know what was happening, because Boeing hadn’t properly disclosed the software to airlines partly to save money, but also to bring the 737 Max to market more quickly.
The House Committee on Transportation and Infrastructure has launched an investigation into the FAA’s certification process, and US transportation secretary Elaine Chao convened a committee to do the same. Chao had also previously asked the Department of Transportation’s inspector general to examine the FAA’s certification process.
