What to do
Operators must recalculate the total life consumed of each affected part within 60 days of 4 December 2023, following the instructions in the specified Rolls-Royce NMSB. Parts exceeding their declared safe cyclic life must be replaced with serviceable parts before further operation. Additionally, only serviceable affected parts may be installed on engines or aircraft from the effective date.
Summary
EASA Airworthiness Directive 2023-0203 is issued for Rolls-Royce Deutschland RB211-535E4 series engines installed on Boeing 757 aircraft among others. The directive addresses recalculation and replacement requirements for critical engine parts to ensure continued airworthiness. It mandates operators to reassess the life consumed by affected parts and replace them if necessary to prevent potential failures.
What changed
This directive introduces updated instructions for recalculating the total life consumed of critical engine parts based on Rolls-Royce Alert Non-Modification Service Bulletin RB.211-72-AH972 Revision 4. It also reintroduces specific part installation requirements and clarifies that EASA AD 2022-0235 remains in effect. The list of critical parts requiring life recalculation has been updated and reorganized by Rolls-Royce Deutschland.
Why it matters
The directive is crucial for aviation professionals as it addresses the risk of critical part failure due to operation beyond assumed flight profiles, which can lead to high-energy debris release and potential damage or injury. Compliance ensures engine safety and regulatory adherence, impacting operators, maintenance organizations, and compliance teams responsible for engine lifecycle management.
