What to do
Operators must perform visual inspections of the affected drains mast parts within 24 months of the effective date or first engine operation, whichever is later, and repeat inspections every 24 months. If cracks are found, immediate sealing is required before the next flight, followed by part replacement within 100 engine flight cycles. Only serviceable parts may be installed on engines and aircraft from the specified dates.
Summary
EASA Airworthiness Directive 2018-0185 is an airworthiness directive addressing Rolls-Royce RB211 Trent 970-84, 972-84, and 972E-84 engines, commonly installed on Airbus A380 aircraft. The directive mandates inspections and potential replacement of specific drains mast parts to prevent cracks that could compromise the engine fire wall. This directive ensures continued airworthiness and safety of affected engines by requiring repetitive inspections and corrective actions.
What changed
EASA Airworthiness Directive 2018-0185 supersedes the previous AD 2017-0075R1 and expands the scope to include engines with pre-mod 80-H632 vent ejector installed and drains mast part number FW29847 (pre-mod 72-H499). It introduces repetitive inspections of all affected engines rather than a one-time inspection and includes additional affected parts to enhance safety measures.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition where cracks in the drains mast could lead to a fire wall breach and uncontrolled fire, risking aircraft safety. Operators and maintenance organizations must comply to prevent engine damage and ensure regulatory compliance. The directive helps maintain fleet safety and avoid operational disruptions due to unplanned repairs or incidents.
