The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model MD-90-30 airplanes. This proposed AD was prompted by reports indicating that certain center wing stringers and skins have been identified to potentially be susceptible to cracking. This proposed AD would require repetitive eddy current, low frequency (ETLF) inspections of the left and right side fastener holes for any crack; repetitive eddy current, high frequency (ETHF) inspections of the lower skin for any crack; and repair if any crack is found. The FAA is proposing this AD to address the unsafe condition on these products.
