📚 After Reports of Mid-Air Emergencies, US Will Audit Boeing's Oversight of 737 Max

"Boeing's troubled 737 MAX planes — which have twice crashed, killing 346 people — have experienced at least six mid-air emergencies and dozens of groundings in the year after an extensive probe cleared them to fly," reports Australia's public broadcaster ABC News: The incidents, pulled from U.S. government air safety databases, are among more than 60 mid-flight problems reported by pilots in the 12 months after the US Federal Aviation Administration (FAA) recertified the plane's airworthiness in late 2020. Former employees of both Boeing and the FAA characterised the reports — which included engine shutdowns and pilots losing partial control of the plane — as serious and with the potential to end in tragedy. In one incident in December 2021, a United Airlines pilot declared a mayday after the system controlling the pitch and altitude of the plane started malfunctioning... The MAX's flight control system also failed on 22 separate flights, a problem which became the primary focus of the FAA's 20-month recertification effort after the two fatal crashes. More than 42 incidents involved equipment malfunctions, and on more than 40 occasions, flight crews chose to ground the affected aircraft while problems were fixed.... Some planes also had a multitude of problems. One Alaskan Airlines MAX-9 was grounded seven times over five months due to malfunctions with its navigation or communication equipment. A Boeing spokeswoman told the ABC, "none of the reports indicate a trend". "In fact, the in-service reliability of the 737 MAX is consistent with other commercial airplane models," the spokeswoman said. "Since November 2020, the 737 MAX has flown more than 1.5 million flight hours in more than 580,000 revenue flights. The overwhelming majority of these flights have been conducted without any incident." Former senior Boeing manager Ed Pierson — who worked at the 737 MAX factory in Seattle between 2015 and 2018 — told ABC "There are a lot of similarities between what we're seeing in some of the reports with what happened during these two crashes." The article also reports that America's Federal Aviation Administration "has now confirmed it did not investigate Boeing's alleged production problems after the crashes." Later the article adds that the U.S. government "will announce a new audit examining Boeing's production oversight of the 737 MAX planes."
