What to do
Operators and maintenance teams must verify that any installation or reinstallation of affected lubrication/scavenge oil pumps on Trent 7000 engines meets the installation criteria specified in Rolls-Royce Alert NMSB TRENT 1000 79-AK868. For Group 1 engines, compliance dates back to 12 February 2024, and for Group 2 engines, compliance begins from the effective date of this AD. Comments on the proposal must be submitted by 15 July 2026.
Summary
EASA Airworthiness Directive PAD No. 26-073 is a proposed directive addressing installation criteria for lubrication and scavenge oil pumps on Rolls-Royce Trent 7000 series engines, which power Airbus A330 (NEO) aircraft. The directive applies to specific part numbers of oil pumps installed on Trent 7000-68, -70, -72, -72C, and -72D engines. It aims to ensure proper installation to prevent engine failures related to low oil pressure.
What changed
This proposed AD supersedes EASA AD 2024-0029 and expands the applicability to include additional Trent 7000 engine variants (Group 2 engines). It retains the installation criteria requirements from the previous AD but now requires compliance for a broader range of engines potentially affected by early-life failure of the oil pump internal eccentric ring or gerotor.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk of in-flight engine shutdowns caused by oil pump failures. Operators and maintenance organizations must ensure that affected parts meet installation criteria to prevent engine malfunctions that could compromise aircraft control. Compliance helps maintain engine reliability and airworthiness, reducing operational disruptions and safety hazards.
