AVIATION: The Boeing 737 MAX has been grounded for almost 10 months, and the furor over the passenger jet’s deadly track record is expected to drag well into 2020. Boeing Chairman David Calhoun is set to become the company’s CEO next week, after Dennis Muilenburg was ousted just before Christmas. The FAA is plugging away at a review of fixes to the plane, while Congress continues to weigh possible changes to the regulator’s certification processes. Committees in both chambers have held multiple hearings digging into how the FAA approved the MAX and let it stay in the air after a first crash off the coast of Indonesia, and more hearings are expected this year. Lawmakers are also awaiting the results of several probes, including the investigation into the second crash in Ethiopia, a DOT inspector general audit and a review of the FAA’s certification process by a DOT panel of aviation experts.
