Boeing’s ongoing 737 Max problems is going on and another safety issue come to light this week, resulting in further flight cancellations by U.S. carriers with the aircraft in their fleets.
United Airlines announced that it has extended previous cancellations to September 3. Meanwhile, Southwest Airlines, which previously announced the cancellations through the beginning of September, said in a statement Thursday that it was removing 737 Max flights from its schedule through Oct. 1. The airline said the changes would affect roughly 150 flights per day.
The announcements from United Airlines and Southwest Airlines come amid reports that test pilots with the Federal Aviation Administration discovered a new critical safety issue with the 737 Max’s anti-stall software system, called MCAS, during flight simulations. According to a source familiar with the matter who spoke to the Washington Post, these pilots were worried they weren’t able to “quickly and easily follow the required recovery procedures.
The FAA said in a statement Wednesday that it found a potential risk that Boeing must mitigate. The Washington Post reported the flaw as being separate from the one suspected to have played a major role in two 737 Max crashes that resulted in the deaths of 346 people.
Boeing said that it was working on a fix for the software issue that would reduce pilot workload by accounting for a potential source of uncommanded stabilizer motion.
During the review of the 737 MAX software update and recent simulator sessions, the Federal Aviation Administration (FAA) identified an additional requirement that it has asked the company to address through the software changes that the company has been developing for the past eight months
