EASA AD 2025-0128R1
Engine — Main Fuel Hose Assembly / Fuel Hoses — Inspection
Summary
EASA Airworthiness Directive 2025-0128R1 is a regulatory document addressing inspection requirements for the main fuel hose assemblies on Rolls-Royce Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 engines, commonly installed on Airbus A350 aircraft. The directive mandates repetitive inspections and corrective actions to detect and mitigate fuel hose degradation that could lead to engine fires and damage. It applies to specific engine serial numbers listed in Rolls-Royce Non-Modification Service Bulletin Trent XWB 72-AL167 Revision 2.
What Changed
This revision of EASA AD 2025-0128 reduces the population of Trent XWB-97 engines subject to inspection by excluding certain engine serial numbers originally listed in Group G of the service bulletin. It retains the previous requirements for repetitive inspections and corrective actions while updating compliance timelines and affected engine groups. The directive continues to enforce inspection protocols introduced in earlier ADs to address fuel hose degradation caused by a suspect cleaning process.
Why It Matters
This directive is critical for aviation professionals as it ensures the early detection of fuel hose damage that could cause engine fires, potentially leading to in-flight shutdowns and aircraft damage. Operators and maintenance organizations must comply to maintain airworthiness and safety, preventing costly unscheduled repairs and operational disruptions. The AD also enforces maintenance process controls by addressing issues related to a suspect cleaning procedure during engine refurbishment.
What To Do
Operators of affected Rolls-Royce Trent XWB engines must perform on-wing inspections within specified compliance times based on engine group and service life, following instructions in Rolls-Royce NMSB Trent XWB 72-AL165 and 72-AL167. Any detected discrepancies require prompt replacement of the affected fuel hose with a serviceable part. Additionally, during any shop visit, affected parts must be inspected and corrected before engine release to service. Compliance deadlines vary by engine group, with some inspections required within days or weeks of the directive's effective dates.
