At least two other carriers - Korea Air Lines and Japan Airlines - said they planned to carry out voluntary inspections of the engines.
In line with recommendations made earlier by engine maker CFM, the FAA ordered that all CFM56-7B engines that have performed 30,000 or more total accumulated flight cycles be inspected within 20 days.
She said a lot of people made hard decisions.
There was evidence of metal fatigue where the blade attached to a hub, Sumwalt said. The FAA made these checks mandatory for some engines shortly afterward in an "emergency" order, depending on how many times they've been used.
CFM International, a joint wander of General Electric and France's Safran Aircraft Engines, fabricated the CFM56-7B motor, which lost one of its fan sharp edges on Southwest Flight 1380 in the blink of an eye into a NY to Dallas stumble on Tuesday morning.
"The inspection, conducted on-wing with an ultrasonic probe along the surface of the fan blade, takes about four hours per engine", the manufacturer said.
Other passengers began trying to plug the hole with jackets and other objects but to no avail.
The 43-year-old community leader and mother of two had been heading home from a business trip Tuesday on a flight from New York's LaGuardia Airport bound for Dallas. Pilot error is one of the top causes of plane crashes.
"I just wanted to make sure I didn't preclude anything by taking the voucher or the check", he said. Shults was said to have shown nerves of steel; proof, yet again, that high-risk jobs can be taken by both men and women. But the fact that this was the only passenger to have ever died on Southwest flights since the pioneering low-priced carrier was founded in 1967 and when the airline carries over 120 million passengers a year, shows that what occurred is the rare exception. CFM, which issued a warning about the possibility of flaws in the fan blades a year ago, reported that it has manufactured 30,000 of the engines.
Riordan was sitting on the left side of the plane when something in the engine apparently broke and smacked into the window.
CFM recommended that fan blades with 20,000 cycles should be inspected by the end of August.
That directive was anticipated to impact 220 engines, although in a comment responding to the FAA proposal Southwest said the number of engines that would need to be tested was well beyond that number, because it didn't track the wear on the individual fan blades in engines.
"This is a sad day and our hearts go out to the family and the loved ones of the deceased customer", he said.
"Hopefully Jennifer knew that she wasn't alone". "We will do all that we can to support them during this very hard time". "My brother says she's the best pilot he knows".
She said the paths are similar for other industries and working conditions are no more a roadblock in aviation.
