What to do
Operators must perform initial inspections within specified flight cycle thresholds or within 50 engine flight cycles after the effective date, then continue inspections every 200 engine flight cycles. If cracks are found, engines must be removed from service within compliance times based on crack severity and repaired or replaced with serviceable parts before return to service. Compliance with the AD is mandatory from 5 September 2024.
Summary
EASA Airworthiness Directive 2024-0167 is issued for Rolls-Royce Deutschland Ltd & Co KG Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84 engines, commonly installed on Airbus A350 aircraft. The directive mandates inspections of the intermediate pressure compressor rotor 1 blades, part number KH21559, to detect cracks and prevent potential engine failures. This AD updates previous requirements to enhance inspection procedures and corrective actions.
What changed
EASA Airworthiness Directive 2024-0167 supersedes AD 2020-0277 and introduces enhanced inspection instructions with improved crack measurement and fly-on criteria. It requires repetitive on-wing or in-shop inspections at specified intervals and mandates removal of engines from service based on crack severity. The directive retains some previous requirements but updates compliance thresholds and corrective actions.
Why it matters
This directive is critical for aviation professionals to prevent intermediate pressure compressor blade failures that could lead to engine in-flight shutdowns and reduced aircraft control. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The enhanced inspection criteria improve detection accuracy, reducing the risk of undetected cracks and subsequent engine damage.
