According to CNBC, the Federal Aviation Administration has certified Boeing's 737 Max 7 after nearly a decade of delays. The agency said the approval followed years of work to resolve technical issues and complete a review of the aircraft's design and safety analyses, and that it required updates to the flight-control software, flightcrew alerting system and a redesigned engine anti-ice system. The changes were made to address requirements in the Aircraft Certification, Safety, and Accountability Act and NTSB recommendations, and to prevent the engine from overheating. Carriers including Southwest Airlines had expected to fly the plane before the pandemic, but certification was delayed by tighter regulatory scrutiny after the fatal 2018 and 2019 crashes of the Max 8 and other safety and manufacturing problems. Boeing is still awaiting FAA certification for the 737 Max 10 and the 777X, while it works to increase production of its 737 Max jets and 787 Dreamliners.
