Three days after a fatal accident on a Southwest Airlines flight involving a faulty engine, the Federal Aviation Administration on Friday issued an emergency order for airlines to conduct emergency inspections of some engines of the same type as the one that exploded on the Southwest plane.

Ms Riordan was the first passenger to die in an accident on a USA commercial airliner since 2009.

Southwest said it needed more time, and it raised concern over the number of engines it would need to inspect.

Engines with over 30,000 total cycles from new must complete the inspections within 20 days, the FAA said.

The order passed about the investigation will be affecting about 680 engines globally including about 350 in the United States as reported by FAA.

The European Aviation Safety Agency is adopting similar requirements, said a person familiar with the matter.

In August, the Federal Aviation Administration proposed making ultrasonic inspections of the fan blades in Boeing 737 aircraft engines mandatory.

In March, an Arik flight from Lagos to Accra, Ghana, made an emergency landing after the pilot detected a smoke in the cabin. A time of 20 days have been provided for the entire inspection process.

Jennifer Riordan had two children.




The transport ministry on Saturday ordered Japanese airlines to make the emergency inspections.

The National Transportation Safety Board said an engine fan blade on Flight 1380 suffered metal fatigue before breaking.

U.S. national security researchers have explained the naked eye can not detect the fractures and indicators of metal fatigue which doomed the engine on Southwest Flight 1380. The EASA had rejected a request by one airline to double the time allowed for checks to 18 months, saying the data did not justify it.

The engines that must be inspected are manufactured by CFM International. The NSTB has however declined to comment on Friday.

The FAA and NTSB have different roles.

The airline's CEO Gary Kelly sent a letter to the 142 passengers who survived, apologizing for the "circumstances" which surrounded the flight and offering their help reuniting them with luggage.

The manufacturer had issued two service bulletins a year ago calling for additional inspections of fan blades on the CFM56-7B engines following a similar episode in 2016 on another Southwest plane.

Nearly 700 Boeing 737 engines will need to be inspected worldwide over the next 20 days, regulators say.
