With the Boeing 737 MAX groundings continuing for almost a full year now, regulators are scrutinizing and looking at every aspect of the jet, making sure the-once hailed “game changer” aircraft is as safe as possible. After an internal audit, requested by the Federal Aviation Administration (FAA) in December 2019, a new, potentially deadly flaw was discovered with the MAX’s wiring systems that control the tail of the jet, reports The New York Times.
