The European Aviation Safety Agency and the Federal Aviation Administration are requiring all Boeing 737NG operators in Europe and the U.S. nearly to double the frequency of repetitive ultrasonic or (in the case of the FAA) eddy current inspections of each fan blade in the CFM56-7B engines powering their 737s.
