EASA AD 2023-0152
Engine — Low Pressure Compressor Booster Rotor — Inspection
Summary
EASA Airworthiness Directive 2023-0152 is an airworthiness directive addressing inspection requirements for the low pressure compressor booster rotors on Rolls-Royce Deutschland BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 engines, commonly installed on Boeing 717 aircraft. The directive mandates fluorescent-penetrant inspections of specific affected parts to detect malformed scallop edge geometry and surface conditions that could lead to engine failure. It provides updated inspection intervals and corrective actions to ensure continued airworthiness.
What Changed
EASA Airworthiness Directive 2023-0152 supersedes the previous AD 2022-0252R1 and introduces revised compliance times for initial and repetitive inspections based on flight mission types. It extends the safe-to-operate period for Hawaiian flight missions and reduces inspection intervals for other flight missions. The directive also mandates the use of updated inspection instructions from the Engine Manual and the Rolls-Royce Deutschland Alert Non-Modification Service Bulletin Revision 1.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent potential engine failures caused by defects in the low pressure compressor booster rotor. Adhering to the updated inspection intervals and corrective actions reduces the risk of in-flight engine shutdowns and enhances flight safety. Compliance ensures regulatory adherence and avoids operational disruptions due to unplanned engine removals.
What To Do
Operators must perform fluorescent-penetrant inspections of the affected low pressure compressor booster rotors within specified compliance times, not later than 31 August 2023, and at intervals depending on the flight mission profile. If cracks are detected during inspections, engines must be removed from service and repaired following Rolls-Royce Deutschland approved procedures before return to service. Installation of affected parts is permitted only if they meet the specified flight cycle limits or have passed the required inspections.
