Applicability*9
Model 777-200 and -300 series airplanes, equipped with Rolls-Royce Model Trent 800 series engines; certificated in any category.
Compliance
Required as indicated, unless accomplished previously. To prevent ingestion of ice that could cause shutdown of both engines during icing conditions, and result in a forced landing of the airplane; accomplish the following: Airplane Flight Manual (AFM) Revision (a) Within 14 days after the effective date of this AD, revise the Limitations Section of the AFM per the following actions specified in paragraphs (a)(1) and (a)(2) of this AD (this may be accomplished by inserting a copy of this AD into the AFM): (1) Remove the following wording from the Limitations Section of the AFM: “Engine anti-ice must be ON during all ground operations, and either ON or in AUTO during flight, when icing conditions exist or are anticipated, except when the temperature is below −40 degrees C OAT. The primary ice detection system (if operative) will automatically turn the engine anti-ice system on and off as required in response to ice detection signals (flight mode only). Do not use anti-ice if OAT or TAT exceeds 10 degrees C (50 degrees F).” (2) Insert the following wording into the Limitations Section of the AFM: “Engine anti-ice must be ON during all ground and flight operations when icing conditions exist or are anticipated, except when the temperature is below −40 degrees C OAT. Do not use anti-ice if OAT or TAT exceeds 10 degrees C (50 degrees F).” Alternative Methods of Compliance (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Seattle ACO. Note: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO. Special Flight Permits (c) Special flight permits may be issued in accordance with §§ 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
