The Federal Aviation Administration is working with NASA and international aviation regulators on a joint task force to review Boeing's fix for its popular 737 Max jets, the FAA said Wednesday.

The Joint Authorities Technical Review team, or JATR, will evaluate the automated flight control system, or MCAS, many people suspect may have caused two fatal crashes of the popular jets that killed 346 people since October.

Chaired by former National Transportation Safety Board Chairman Chris Hart, the task force will also review the MCAS' "design and pilots' interaction with the system, to determine its compliance with all applicable regulations and to identify future enhancements that might be needed," the FAA said.
