A new computer problem has been found in the troubled Boeing 737 Max that will further delay the plane's return to flying after two deadly crashes, according to two people familiar with the matter.
The latest flaw in the plane's computer system was discovered by Federal Aviation Administration pilots who were testing an update to critical software in a flight simulator last week at a Boeing facility near Seattle, the people said.
Boeing did not immediately respond to a request for comment.
One of the people familiar with the discovery said it would add one to three months to the timetable for returning the Max to flight. Both spoke on condition of anonymity because the development has not been made public.
