Travelers are feeling the effects of the Federal Aviation Administration’s grounding order for some Boeing 737 Max 9s, with hundreds of flights canceled since Saturday and more expected as aircraft inspections continue. The FAA directive responded to an explosive depressurization accident Friday night in which a section of an Alaska Airlines plane’s wall ripped off midflight, leaving a gaping hole in the side of the aircraft.
Thousands of passengers face flight cancellations after major US airlines grounded dozens of Boeing jets after a mid-flight blowout over Oregon.
The US aviation regulator said 171 Boeing 737 Max 9s must be grounded for checks after part of an Alaska Airlines plane’s fuselage fell off on Friday.
Alaska said flight disruptions are expected to last into next week. United Airlines has grounded 79 planes.
Disruptions are likely to primarily affect flights in the US.
It follows regulator the Federal Aviation Administration (FAA) ordering “immediate inspections” of 737 Max 9s worldwide.
Required inspections would take around four to eight hours per aircraft, it said.
The European Union Aviation Safety Agency (EASA) is following the FAA approach, but flight disruptions on the continent are expected to be minimal.
EASA said it believes no European airlines operate Max 9s with the configuration covered by the FAA order.
One of the world’s largest intercontinental airports, London Heathrow, said there was no impact on flights.
The bulk of the affected planes are owned by US airlines. United Airlines has grounded all 79 of its Max 9 planes.
Alaska said it cancelled 160 flights on Saturday, affecting about 23,000 passengers.
Other airlines which also fly the planes have temporarily taken them out of service.
Boeing said it welcomed the FAA’s decision, adding its teams were in close contact with the regulator.
During Friday’s incident, Alaska Airlines flight 1282 from Portland, Oregon, to Ontario, California, reached 16,000ft (4,876m) when it began an emergency descent, according to flight tracking data.
Passengers on board said a large section of the plane’s outer shell fell to the ground shortly after take-off.
Images sent to news outlets show the night sky and lights of Portland visible through the gap in the fuselage, with insulation material and other debris also seen.
One passenger said the gap was “as wide as a refrigerator” while another said a child’s shirt was ripped off in the wind as the plane made its emergency landing
