Boeing 737 Max 9: Most of the blocked machines are allowed to fly again. Almost all machines are now back in operation, but there are still problems with production.
Of the 144 aircraft affected in the United States, 135 were inspected and returned to service. The US Federal Aviation Administration (FAA) had previously banned Boeing from expanding production of the aircraft. The incident also had far-reaching consequences for Alaska Airlines and United Airlines, the two US airlines that use the affected aircraft.
