The LCSO is helping two federal agencies, the National Transportation Safety Board and the Federal Aviation Administration, in their crash investigation.
The FAA held a meeting Thursday in Fort Worth, Texas, with nearly 60 officials from more than 30 countries to explain its process for analyzing Boeing's changes to the Max.
The list of foreign regulators includes delegates from Indonesia and Ethiopia, where the two crashes occurred before the plane was grounded worldwide in March. In all, 346 people died.
The Federal Aviation Administration will consider a recommendation next week that it ease restrictions on airline passengers' use of smartphones, tablets and other personal electronic devices during takeoffs and landings.
