Applicability*9
This AD applies to all GEnx-1B64, -1B64/P1, -1B64/P2, -1B67, -1B67/P1, -1B67/P2, -1B70, 1B70/P1, -1B70/P2, -1B70/75/P1, -1B70/75/P2, -1B70C/P1, -1B70C/P2, -1B74/75/P1, -1B74/75/P2, -1B76A/P2 engines with outer left side signal fuel manifold, part number (P/N) 2403M46G01, and CAGE code 05813, installed.
Compliance
Comply with this AD within the compliance times specified, unless already done. (1) Inspect the outer left side signal fuel manifold, P/N 2403M46G01 and CAGE code 05813, to determine if the part has additional marking “XB,” “INS,” or “KB” adjacent to part number. If the part is marked with “XB,” “INS,” or “KB,” then no further action is required. (2) For parts without additional marking “XB,” “INS,” or “KB” adjacent to the part number, within 12 months after the effective date of this AD, replace the outer left side signal fuel manifold with a part eligible for installation.
Required actions
After the effective date of this AD, do not install an outer left side signal fuel manifold, P/N 2403M46G01, and CAGE code 05813, onto an engine, unless additional marking “XB,” “INS,” or “KB” is adjacent to the part number.
Unsafe condition
This AD was prompted by fracture of the fuel manifold which led to an in-flight shutdown of the engine. We are issuing this AD to prevent fracture of the fuel manifold, engine fire, and damage to the airplane.
Affected ADs
None.

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.
