Boeing Co's BA 737 MAX jets may be ungrounded next week as the United States Federal Aviation Administration is in the final stages of reviewing changes to the jet, Reuters reported Monday. What Happened: Three sources familiar with the matter told the newswire that the planes may be allowed back into the skies as early as Nov. 18. FAA Administrator Steve Dickson that the process will be "finished in the coming days, once the agency is satisfied that Boeing has addressed" safety issues related to fatal crashes that took the lives of 346 people. Dickson disclosed that the FAA was engaged with aviation authorities "around the world" as they prepare to validate its certification decision. After the FAA gives its approval, airlines will have to carry out software upgrades and fresh pilot training that could take at least 30 days, noted Reuters. Why It Matters: China's aviation regulator has reportedly not yet committed a time frame for the plane's return to service.
