EASA AD 2019-0282R1
Engine — Intermediate Pressure Compressor Shaft Assembly — Inspection
Summary
EASA Airworthiness Directive 2019-0282R1 is a regulatory document addressing inspection requirements for the intermediate pressure compressor (IPC) shaft assembly, part number KH18436, installed on Rolls-Royce Trent 1000 and Trent 7000 engines. These engines are commonly found on Boeing 787 and Airbus A330 aircraft. The directive mandates repetitive inspections to detect cracks in the IPC shaft assembly's front air seal to prevent potential engine failure.
What Changed
This revision excludes engines modified with Rolls-Royce modifications 72-K570 or 72-K571 from the inspection applicability. It introduces the applicable Rolls-Royce Service Bulletins as optional terminating actions for the repetitive inspections and adds reference to an alternative inspection method provided by Rolls-Royce NMSB 72-K618. The directive updates compliance instructions and clarifies acceptable inspection procedures.
Why It Matters
This directive is critical for aviation professionals to prevent engine in-flight shutdowns caused by IPC shaft assembly cracks, which could compromise aircraft control. Operators and maintenance organizations must ensure compliance to maintain airworthiness and avoid unplanned engine removals. The clear inspection intervals and corrective action requirements help streamline maintenance planning and enhance safety.
What To Do
Operators must perform initial inspections of the affected IPC shaft assembly within specified flight cycle limits and continue inspections every 200 flight cycles thereafter. If cracks are found, the engine must be removed from service before the next flight and repaired following Rolls-Royce approved instructions. Modification of engines using the specified service bulletins can terminate the inspection requirements. Installation of affected parts is only allowed if they are serviceable as defined in the directive.
