## Abstract

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. This AD was prompted by reports of corrosion in the aft fuselage. This AD requires a one-time review of the operator's maintenance procedures, repetitive detailed internal and external inspections for corrosion or cracking, and applicable on-condition actions. This AD also includes an optional terminating action for the inspections. We are issuing this AD to address the unsafe condition on these products.
