The NTSB will look into how an interior crack on a fan blade could have led to the engine failure. Sumwalt said it was "certainly not detectable from looking at it from the outside."The crack was found in a fan blade of the CFM International 56-7B turbofan engine that separated during the incident.The blade had broken twice, where the blade attached to a hub and almost halfway through it, Sumwalt said.One of the cracks was consistent with metal fatigue, he said.Manufacturers regularly inspect engines for hidden cracks using X-ray machines or ultrasound devices -- the same kind of technology doctors use to check the health of expectant mothers.Southwest Airlines said in an email Wednesday that workers did a visual inspection of the engine that failed. An ultrasonic inspection of engine was scheduled to take place this December.The Federal Aviation Administration said Wednesday night it will issue a directive in the next two weeks requiring inspections of certain CFM56-7B engines. The directive will require an ultrasonic inspection of fan blades when they reach a fixed number of cycles. 1101
