This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2006-20-51 that was sent previously to all known U.S. owners and operators of certain Boeing Model 777-200LR and -300ER series airplanes by individual notices. This AD requires revising the Airplane Flight Manual to prohibit takeoffs at less than full-rated thrust. This AD is prompted by a report of two occurrences of engine thrust rollback (reduction) during takeoff. We are issuing this AD to prevent dual-engine thrust rollback, which could result in the airplane failing to lift off before reaching the end of the runway or failing to clear obstacles below the takeoff flight path.
