What the agency says
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200LR and -300ER series airplanes. This AD was prompted by reports of chafing and arcing damage on the light emitting diode (LED) sidewall wire bundles. This AD requires a general visual inspection (GVI) of the sidewall light for chafing damage and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
