EASA AD 2022-0129
Engine — Front Engine Mount Support Structure — Inspection
Summary
EASA Airworthiness Directive 2022-0129 is an airworthiness directive addressing the inspection of the front engine mount support structure on Rolls-Royce Trent XWB series engines, including Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 models. These engines are commonly installed on Airbus A350 aircraft. The directive mandates inspections of the low pressure compressor outlet guide vane outer mount ring assembly to prevent potential engine mount failure.
What Changed
EASA Airworthiness Directive 2022-0129 supersedes the previous AD 2019-0234, expanding applicability to include Trent XWB-97 engines. It removes the requirement for on-wing inspections and aligns the inspection interval with qualified shop visits. The directive updates inspection procedures based on revised analysis and new Rolls-Royce service bulletins.
Why It Matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition that could lead to engine mount support structure failure and possible engine separation, which would severely impact aircraft control. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and airworthiness. The updated inspection intervals and procedures optimize maintenance planning and reduce unnecessary inspections.
What To Do
Operators must perform inspections of the outlet guide vane outer mount ring assembly during each qualified shop visit after 14 July 2022, following the instructions in the applicable Rolls-Royce Alert Non-Modification Service Bulletins. If any discrepancies exceeding acceptance criteria are found, corrective actions such as replacement or repair must be completed before engine release. No terminating action is provided, so inspections must continue at each qualified shop visit.
