AD FAA-2019-0866

The FAA is superseding Airworthiness Directive (AD) 2019-20- 02, which applied to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2019-20-02 required repetitive inspections for cracking of the left- and right-hand side outboard chords of frame fittings and failsafe straps at a certain station around two fasteners, and repair if any cracking is found. This AD also requires repetitive inspections for cracking of the left- and right-hand side outboard chords of frame fittings and failsafe straps at a certain station, but expands the inspection to the area around eight fasteners, and also requires repair if any cracking is found. This AD was prompted by a determination that the inspection area needs to be expanded. The FAA is issuing this AD to address the unsafe condition on these products.
