The US Federal Aviation Administration (FAA) on Wednesday (native time) barred troubled planemaker Boeing from increasing production of its 737 MAX plane due to “unacceptable” high quality points, information company Reuters reported.

In one other vital resolution, the FAA gave its nod to permit 737 MAX 9, which was grounded after a mid-air blowout on Alaska Airlines earlier this month, to resume its flying operations after inspections have been accomplished.
