The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by a report of cracks found in fastener holes at a certain station of the center wing box. This proposed AD would require repetitive external surface high frequency eddy current inspections (HFEC) and repetitive external surface ultrasonic inspections; or repetitive internal detailed inspections; of a certain station of the center wing box for any cracking, and repair if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
