Docket No. 2002-NM-318-AD
Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 777 series airplanes. This action requires revising the Airplane Flight Manual to specify that the engine anti-ice must be "on" during all ground and flight operations when icing conditions exist or are anticipated. This action is necessary to prevent ingestion of ice that could cause shutdown of both engines during operation in icing conditions, and result in a forced landing of the airplane.
