Summary
The FAA is superseding Airworthiness Directive (AD) 2017-16- 10, which applied to all The Boeing Company Model 777 airplanes. AD 2017-16-10 required repetitive inspections of the left and right side underwing longerons for any crack, and related investigative and corrective actions if necessary. This AD retains the requirements of AD 2017-16-10, reduces certain compliance times for certain airplanes, and removes airplanes from the applicability. This AD was prompted by reports of cracks on the underwing longerons. The FAA is issuing this AD to address the unsafe condition on these products.
