(CNN) US and European aviation authorities have ordered inspections within the next 20 days for almost 700 engines similar to the one that failed earlier in the week on a Southwest Airlines flight, resulting in a passenger's death. The US Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA) each issued an emergency airworthiness directive Friday requiring airlines to perform an ultrasonic inspection of certain CFM56-7B engines. About 20 minutes into the flight, at about 32,500 feet, a fan blade broke off the engine and shrapnel shattered a window. Jennifer Riordan, 43, and a mother of two, was almost sucked out of the broken window and pulled back inside by fellow passengers. The FAA and EASA directives came on the same day that the engine manufacturer, CFM International, issued a service bulletin recommending the CFM56-7B engine be inspected more frequently.
