What to do
Operators of affected Rolls-Royce RB211 Trent 970-84, 972-84, and 972E-84 engines must modify the P30 air system according to the specified Service Bulletin within 11 months from 1 June 2021 for Group 1 engines, or before release to service after certain modifications for Group 2 engines. Installation of affected parts is prohibited after modification or from 1 June 2021 for Group 3 engines. Compliance with the updated Service Bulletins is required to meet the AD.
Summary
EASA Airworthiness Directive 2021-0129R1 is a regulatory update addressing the modification of the Low Pressure Compressor Case Static P30 Air System on Rolls-Royce RB211 Trent 970-84, Trent 972-84, and Trent 972E-84 engines, commonly installed on Airbus A380 aircraft. The directive mandates changes to the P30 air system to prevent discrepancies in engine control signals that could affect thrust delivery. It applies to all serial numbers of the specified engine models.
What changed
This revision clarifies that later approved revisions of certain Rolls-Royce Service Bulletins can be used for compliance, without requiring the original versions. It updates compliance instructions and confirms that the prohibition on installing affected parts applies to specific engine groups. The AD revises the original 2021 directive to improve clarity and compliance flexibility.
Why it matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition where incorrect P30 air system signals could cause thrust deviations, impacting aircraft control. Operators and maintenance organizations must ensure compliance to maintain engine reliability and safety. The AD also affects parts installation policies, preventing the use of outdated components that could compromise engine performance.
