What to do
Operators must perform on-wing inspections within 1,000 flight cycles from new or last inspection and repeat every 1,000 flight cycles thereafter. In-shop inspections are required at every engine shop visit starting from 12 December 2025, with immediate corrective replacement of any damaged parts before next flight or engine release. Records of inspections must be maintained according to local regulations.
Summary
EASA Airworthiness Directive 2025-0265 is an airworthiness directive addressing inspection requirements for intermediate and high pressure air tubes on Rolls-Royce Trent 7000-72 and Trent 7000-72C engines, commonly installed on Airbus A330 (NEO) aircraft. The directive mandates repetitive on-wing and in-shop visual inspections of specific air transfer and air feed tubes to ensure their structural integrity and prevent potential engine damage.
What changed
This directive supersedes EASA AD 2023-0186 and introduces repetitive on-wing inspections for engines in pre-mod 72-K336 configuration, extending inspection intervals to 1,000 flight cycles. It retains previous inspection requirements while adding new compliance timelines and clarifies inspection procedures based on engine shop visit history.
Why it matters
The directive addresses a safety concern where fractures in critical air tubes may remain undetected, potentially leading to reduced engine cooling efficiency and premature failure of critical engine parts. Compliance ensures continued airworthiness, prevents engine damage, and supports safe operation of affected aircraft, impacting operators, maintenance organizations, and regulatory compliance teams.
