What to do
Affected operators must comply with the AD by performing the required clamp removal, clevis mount replacement, and clamp reinstallation at the next engine shop visit, effective February 17, 2026. Stakeholders should use the latest Pratt & Whitney Alert Service Bulletin PW1000G-C-72-00-0214-00A-930A-D, Issue 006, and may request alternative methods of compliance if justified.
Summary
EASA AD US-2025-26-04 is a final airworthiness directive issued by the FAA addressing International Aero Engines LLC models PW1122G-JM through PW1431GH-JM. It targets hydraulic fuel pressure fuel oil cooler fuel tube assemblies (CP09 tube assembly) and thermal management system clevis mounts to prevent unsafe conditions related to fan blade fractures that have caused engine fires.
What changed
This new airworthiness directive requires removal of one loop cushion clamp from the CP09 tube assembly, replacement of the thermal management system clevis mounts with redesigned versions, and reinstallation of the loop cushion clamp as applicable. It also clarifies definitions such as 'next engine shop visit' and updates referenced service materials to the latest revisions allowing reuse of certain bolts after inspection.
Why it matters
This directive is critical for aviation professionals to prevent fuel leaks and potential uncontrolled engine fires caused by fan blade fractures. Operators and maintenance organizations must comply to ensure continued airworthiness and safety of affected engines, minimizing operational disruptions and avoiding costly damage or accidents.
