EASA SIB 2007-52
Rolls-Royce RB211-524 and -535E4, RB211 Trent 500, 700 and 800 series engines - Group A Parts - Non-compliance with required Magnetic Particle Inspection (MPI) instructions
Summary
EASA Safety Information Notice 2007-52 addresses non-compliance with Magnetic Particle Inspection (MPI) instructions on Rolls-Royce RB211-524, RB211-535E4, and RB211 Trent 500, 700, and 800 series engines. The notice informs that some Group A parts were inspected without removing corrosion protective coatings, which reduces MPI effectiveness. This issue does not affect the engine type design or require additional in-service action.
What Changed
This notice clarifies that MPI inspections performed without removing corrosion protection on certain Group A parts are not compliant with approved maintenance instructions. It confirms that no hazardous failure modes are associated with the affected coated areas and that future MPI inspections must be conducted with corrosion protection removed. No new mandatory inspections or design changes are introduced.
Why It Matters
Aviation professionals need to understand that while some MPI inspections were not fully compliant, the safety and airworthiness of the affected Rolls-Royce engines are not compromised. Operators and maintenance organizations can continue normal operations without immediate corrective action, ensuring confidence in ongoing maintenance practices. This information helps compliance teams prioritize inspections and maintenance planning effectively.
What To Do
Operators and maintenance providers should ensure that future MPI inspections on affected Group A parts of Rolls-Royce RB211-524, RB211-535E4, and Trent 500, 700, and 800 engines are performed only after removing corrosion protective coatings. No immediate removal or additional inspections are required for engines currently in service. Contact Rolls-Royce for lists of affected parts if needed.
