In addition, the aerospace company noted that the FAA discovered the potential risk through recent simulator flights and review of the 737 Max software update.
Furthermore, Boeing said it is working on resolving the flaw and will not offer the 737 Max for certification until it has satisfied all requirements necessary to ensure that the aircraft is safe to fly again.
The FAA grounded all Boeing 737 Max in March after two crashes involving the Lion Air flight 610 and Ethiopian Airlines flight 302. The accidents led to the death of 346 people.
