New software flaw could further delay BOEING MAX

Boeing 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.

The issue involves how software on the plane checks itself to ensure it’s receiving valid data, said a person familiar with the issue who wasn’t authorized to speak publicly about it. It occurs when the system is initially starting up, the person said.

“We are making necessary updates and working with the FAA on submission of this change, and keeping our customers and suppliers informed,” Boeing said in its statement. “Our highest priority is ensuring the 737 MAX is safe and meets all regulatory requirements before it returns to service.”

The FAA didn’t comment directly on the latest issue to arise on the problem-plagued plane. “We continue to work with other international aviation safety regulators to review the proposed changes to the aircraft,” the agency said in an emailed statement. “Our first priority is safety, and we have set no time-frame for when the work will be completed.”
