EASA AD 2025-0288
Engine — Low Pressure Compressor Blades — Removal from Service
Summary
EASA Airworthiness Directive 2025-0288 is an official regulatory document addressing the removal from service of certain low pressure compressor blades installed on Rolls-Royce Deutschland RB211 Trent 700 engines, commonly found on Airbus A330 aircraft. The directive identifies specific part numbers and serial numbers of affected compressor blades that have undergone erroneous repairs, leading to potential blade cracking. It mandates inspections and removal of these parts to ensure continued airworthiness and safety.
What Changed
EASA Airworthiness Directive 2025-0288 supersedes the previous AD 2024-0130 and expands the list of affected low pressure compressor blades by adding nine new serial numbers. It retains the original removal requirements and introduces additional compliance deadlines for the newly identified parts. The directive also prohibits installation of affected parts from specified reference dates and requires replacement of parts with limited remaining life during shop visits.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk involving structural failures of low pressure compressor blades that could lead to in-flight shutdowns, fires, or uncontained debris release. Operators and maintenance organizations must comply to prevent unsafe conditions and ensure regulatory conformity. The expanded scope and updated compliance times require careful tracking of affected parts and timely maintenance actions to avoid operational disruptions.
What To Do
Operators must remove Group A affected compressor blades before exceeding specified cycles or within 30 flight cycles or 30 days after the effective dates, whichever is later. Group B affected parts must also be removed within similar compliance times. During shop visits, parts with 100 or fewer remaining cycles must be replaced with serviceable parts. Installation of affected parts is prohibited from the defined reference dates. Compliance deadlines start from 22 July 2024 for Group A parts and from 31 December 2025 for Group B parts.
