Boeing has discovered a new software vulnerability in the grounded 737 Max that needs to do more to get the plane back on flying. Boeing said in an e-mailed statement that it had notified the Federal Aviation Administration and notified customers and suppliers about the issue.
People familiar with the matter said the problem involved how a software system on board the plane was checked to make sure the data received from other monitors was working properly.
“We are making the necessary updates, working with the FAA to submit this update and inform our customers and suppliers,” Boeing said in a statement. “Our highest priority is to ensure that the 737 MAX is safe and meets all regulatory requirements before it is put back into service. “
