Boeing Co. has identified a new software flaw in the grounded 737 Max that will require additional work, possibly further delaying the plane’s return to service.

The company alerted the U.S. Federal Aviation Administration and is notifying customers and its suppliers, it said in an emailed statement. Boeing’s best-selling jet was grounded on March 13 after two fatal crashes involving a flight-control system.
