What to do
Operators must perform fluorescent-penetrant inspections of the affected low pressure compressor booster rotors within specified compliance times based on flight mission profiles or within 5,000 engine flight cycles after the last approved in-shop inspection. If cracks are found during inspections, the engine must be removed from service and repaired per Rolls-Royce Deutschland approved procedures before return to service. Installation of affected parts is permitted only if they meet the flight cycle limits or have passed the required inspections.
Summary
EASA Airworthiness Directive 2022-0252R1 is a regulatory update addressing inspection requirements for 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 low pressure compressor booster rotors to detect malformed scallop edge geometry and surface conditions that could lead to engine failure. It provides detailed inspection intervals and corrective actions to ensure continued airworthiness.
What changed
This revision amends the inspection compliance times by allowing engines with affected parts that passed an in-shop fluorescent-penetrant inspection before 30 December 2022 to operate for an additional 5,000 engine flight cycles before the next inspection. It also clarifies inspection intervals and conditions for installing affected parts on engines.
Why it matters
This directive is critical for aviation professionals to prevent potential engine failures caused by defects in low pressure compressor booster rotors, which could lead to in-flight shutdowns and reduced aircraft control. Operators and maintenance organizations must adhere to the specified inspection intervals and corrective actions to maintain safety and regulatory compliance. Understanding these requirements helps avoid unplanned downtime and ensures safe operation of affected engines.
