Action
Final rule.
Summary
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This AD was prompted by a report indicating multiple findings of cracks in the fuselage skin common to the underwing longeron (UWL). This AD requires external or internal (depending on configuration) inspections for any cracking of the left and right side fuselage skin common to the UWL, and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
