Here’s what airlines, regulators are doing about Boeing 737 MAX 9 jets

The U.S. aviation regulator has agreed to allow Boeing’s top-selling 737 MAX 9 airplanes to resume flying after inspections, but barred the troubled planemaker from expanding production. The Federal Aviation Administration (FAA)’s move comes after the aircraft had been grounded since a mid-air blowout on an Alaska Airlines jet on Jan. 5.

The airline grounded all 65 of its Boeing 737 MAX 9 planes and cancelled hundreds of flights since the incident. It said on Jan. 8 that initial reports from its technicians indicated some “loose hardware” was visible on some aircraft in the relevant area.
