## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by a report of a frame web crack at fuselage station (STA) 328 between stringers S-20R and S-21R common to the frame web notch. This proposed AD would require repetitive detailed inspections of the forward and aft sides of the frames and high frequency eddy current (HFEC) inspections of the frames for cracks and repairing any crack found. The FAA is proposing this AD to address the unsafe condition on these products.
