Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2019-22-10, which applies to all The Boeing Company Model 737-600, - 700, -700C, -800, -900, and -900ER series airplanes. AD 2019-22-10 requires repetitive inspections for cracking of the left- and right- hand side outboard chords of frame fittings and failsafe straps at a certain station around eight fasteners, and repair if any cracking is found. Since the FAA issued AD 2019-22-10, it was determined that the initial inspection threshold and repetitive inspection interval are inadequate to address the cracking in a timely manner. For certain airplanes, this proposed AD would reduce the compliance time for the initial inspection, and for all airplanes this proposed AD would reduce the compliance time for the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.
