What to do
Operators must perform initial inspections within specified compliance times based on engine flight cycles and continue inspections every 1000 flight cycles thereafter. If any damage is detected, immediate corrective actions including re-inspection or replacement of the affected part must be taken before further flight. Compliance deadlines vary by engine serial number, with some inspections required within three months of the effective date.
Summary
EASA Airworthiness Directive 2019-0234 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning Rolls-Royce Trent XWB series engines installed on Airbus A350 aircraft. The directive mandates inspections of the front engine mount support structure, specifically the low pressure compressor outlet guide vane outer mount ring assembly, to detect potential failures that could lead to engine separation.
What changed
This directive introduces mandatory repetitive inspections of the OGV outer mount ring assembly lug fillet area to identify cracks or damage that could compromise the engine mount's integrity. It requires corrective actions, including part replacement if discrepancies are found, to prevent failure of the engine mount support structure. No previous airworthiness directive is superseded by this AD.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to engine separation and reduced aircraft control. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and airworthiness. Failure to comply could result in serious safety risks and regulatory non-compliance.
