What to do
Operators must inspect all affected fan blades before exceeding specified flight cycle thresholds or within 30 days of the AD effective date, then continue inspections at intervals defined by engine model and flight profile. If cracks exceeding criteria are found, blades must be replaced before further flight. Modification per Rolls-Royce Service Bulletin RB.211-72-C946 is an optional terminating action for repetitive inspections. Compliance with the latest Rolls-Royce Alert NMSB RB.211-72-AC879 Revision 9 is required.
Summary
EASA Airworthiness Directive 2018-0202R1 is a regulatory document addressing the inspection requirements for low pressure compressor fan blades on Rolls-Royce RB211-535E4 series engines, which are installed on aircraft including Boeing 757 and Tupolev TU-204. The directive mandates repetitive inspections to detect cracks in fan blade roots that could lead to blade failure and potential engine debris release. It provides detailed inspection intervals based on engine model and flight profile, along with corrective actions and optional terminating modifications.
What changed
EASA Airworthiness Directive 2018-0202R1 revises the previous AD 2018-0202 by correcting the inspection scope to specify that only affected fan blades must be inspected. It retains the existing inspection requirements and intervals while clarifying compliance details and updating references to the latest Rolls-Royce service bulletin revision. The revision ensures accurate applicability and compliance instructions for operators.
Why it matters
This directive is critical for aviation professionals to prevent fan blade failures that could cause serious engine damage and safety risks. Operators and maintenance organizations must adhere to the inspection intervals and procedures to maintain airworthiness and regulatory compliance. The AD helps mitigate risks associated with crack initiation due to missing anti-frettage coating, ensuring continued safe operation of affected engines.
