The US’ aviation regulator has still not received Boeing’s proposed fix for its 737 MAX aircraft, which have been grounded globally following two deadly crashes, the agency’s chief has said.
Boeing has said it will patch the Maneuvering Characteristics Augmentation System (MCAS) stall prevention system, which has been blamed for the two crashes in Indonesia and Ethiopia that killed a total of 346 people and caused the best-selling planes to be taken out of service.
Boeing said last week that it had finished making changes requested by the US Federal Aviation Administration (FAA), but the agency’s interim chief Dan Elwell told reporters on Wednesday that the agency hadn’t yet seen the fixes.
