The Federal Aviation Administration (FAA) mentioned it had recognized the “potential risk” throughout simulator checks, but didn’t reveal particulars.
Boeing’s top–selling plane was grounded in March after two crashes.
The company is upgrading the plane‘s flight management system, which is the focus of crash investigators.
The management system might help prevent a plane from stalling.
In a tweet, the FAA mentioned: “On the latest difficulty, the FAA’s course of is designed to find and highlight potential risks. The FAA not too long ago discovered a possible threat that Boeing should mitigate.”
Last month, the FAA indicated that approval of Boeing’s changes to the 737 Max may are available in late June. That might have allowed take a look at flights in early July.
There have been initial hopes among airlines that the 737 Max can be again within the air throughout the summer, however that timetable was pushed again to late this year even earlier than the most recent information.
Reuters, which first reported the brand new challenge, mentioned throughout an FAA pilot simulation through which the software program was activated, it had taken longer than anticipated to recover the plane.
Different sources mentioned the issue was linked to the plane‘s computing power and whether or not the processor possessed sufficient capacity to keep up.
Boeing stated “we’re working closely with the FAA to safely return the Max to service” and that it believed a software fix would deal with the issue.
But the FAA will likely be wanting into whether or not it’s a hardware situation.
