The inspectors learned that Boeing had opted to make the malfunction signal optional and an extra that would cost more money.
This came after Southwest asked Boeing to reactivate the signal after the Lion Air crash, which killed all 189 people on board.
Boeing had deactivated the signal on all 737 Max delivered to Southwest without telling the carrier.
Neither the airline nor its pilots were aware of these changes when they started flying the planes in 2017, a spokeswoman for Southwest told AFP.
