US regulator publishes proposed design and software changes for Boeing 737 MAX

The Federal Aviation Administration, America’s civil aviation regulatory body, released a document on Monday detailing changes it wants made to Boeing’s 737 MAX single-aisle airliner before it will allow it to resume commercial operations. The aircraft has been grounded since March 2019, as a consequence of two fatal accidents that killed 346 people. The document is a ‘Notice of Proposed Rulemaking’ (NPRM) and will be published in the Federal Register. Once published, people will have 45 days to submit comments on the FAA’s proposals.
