Airworthiness Directive 2003-03-03
one-timeAirworthiness Directives; Boeing Model 777 Series Airplanes Equipped With Rolls-Royce Model Trent 800 Series Engines
What this AD requires
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.
Which aircraft AD 2003-03-03 applies to
Whether AD 2003-03-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
