What to do
Operators and maintenance personnel must verify that any installation or reinstallation of affected lubrication/scavenge oil pumps on Trent 7000 engines meets the installation criteria defined in Rolls-Royce Alert NMSB TRENT 1000 79-AK868. For Group 1 engines, this requirement applies from 12 February 2024, and for Group 2 engines, from 31 July 2026. Prior determinations made under Revision 3 of the NMSB are accepted for compliance.
Summary
EASA Airworthiness Directive 2026-0141 addresses installation criteria for lubrication and scavenge oil pumps on Rolls-Royce Trent 7000 series engines, which are commonly installed on Airbus A330 NEO aircraft. The directive applies to specific affected parts with certain part numbers and aims to prevent engine in-flight shutdowns caused by early-life failure of internal components in these pumps. It mandates compliance with installation criteria outlined in Rolls-Royce Alert Non-Modification Service Bulletin TRENT 1000 79-AK868.
What changed
EASA Airworthiness Directive 2026-0141 supersedes the previous AD 2024-0029 and expands the applicability to include additional Trent 7000 engine variants (Group 2 engines). It retains the original installation requirements but now requires that affected parts installed on these additional engine models meet the specified installation criteria. The directive also accepts prior compliance with an earlier revision of the referenced service bulletin as valid.
Why it matters
This directive is critical for aviation professionals to prevent potential engine failures that could lead to in-flight shutdowns, thereby enhancing flight safety. Operators and maintenance organizations must ensure that affected oil pumps are installed according to the specified criteria to avoid reduced or loss of aircraft control. Compliance ensures continued airworthiness and regulatory conformity for aircraft equipped with Trent 7000 engines.
