EASA AD 2024-0182R1
SUPERSEDED BY EASA AD 2025-0128
Summary
EASA Airworthiness Directive 2024-0182R1 is a regulatory update addressing inspection and maintenance requirements for Rolls-Royce Trent XWB series engines, specifically models Trent XWB-75, -79, -79B, -84, and -97, installed on Airbus A350 aircraft. The directive focuses on inspecting and replacing certain main fuel hose assemblies identified by specific part numbers to prevent potential engine fires. It mandates repetitive inspections and corrective actions to ensure continued airworthiness of affected engines.
What Changed
EASA Airworthiness Directive 2024-0182R1 revises the previous AD 2024-0182 by incorporating updated instructions from Rolls-Royce Non-Modification Service Bulletin Trent XWB 72-AL167 Revision 1. It clarifies that replacing an affected fuel hose part constitutes terminating action for repetitive inspections and expands the scope to include additional Trent XWB engine models potentially affected by a suspect cleaning process. The revision also updates compliance times and inspection intervals.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety issue involving fuel manifold main fuel hose degradation that could lead to engine fires and in-flight shutdowns. Operators and maintenance organizations must comply to prevent severe engine damage and ensure aircraft safety. The AD also impacts maintenance planning by requiring repetitive inspections and restricting installation of affected parts, influencing operational readiness and maintenance scheduling.
What To Do
Operators and maintenance teams must perform initial and repetitive inspections of the specified fuel hose assemblies within defined compliance times based on engine group and service history. Any discrepancies found must be corrected by replacing affected parts with serviceable ones following Rolls-Royce service bulletin instructions. Replacement of affected parts with new parts after 1 September 2024 terminates the need for further inspections. Compliance deadlines vary by engine group, with some inspections required within days to weeks from the effective date of 3 October 2024.
