Boeing must perform more work on a proposed fix to its 737 MAX aircraft before it can be submitted for review, US officials said Monday, suggesting the planes could stay grounded a while longer. Boeing's 737 MAX planes were grounded globally last month following the second of two deadly crashes to occur in less than five months. After that, the proposal will be submitted to a "rigorous safety review," the FAA spokesman said. A Boeing spokesman said Monday the company was continuing to work with regulators to address concerns. Anti-stall systemA source with knowledge of the investigation has said an anti-stalling system, the Maneuvering Characteristics Augmentation System (MCAS), was activated shortly before the crash.
