EASA AD 2022-0222
Engine Exhaust — Thrust Reverser Lower Beam — Inspection / Repair
Summary
EASA Airworthiness Directive 2022-0222 is an airworthiness directive affecting Airbus A330-243, A330-243F, A330-341, A330-342, A330-343, and A330-743L aeroplanes equipped with Trent 700 engines. It mandates inspections and repairs of the thrust reverser lower beam to address thermal degradation and fatigue issues that could compromise structural integrity. The directive includes detailed inspection procedures and corrective actions to ensure continued airworthiness.
What Changed
EASA Airworthiness Directive 2022-0222 supersedes the previous AD 2018-0148R1 and expands its applicability to include the A330-743L model. It also extends the calendar compliance time and intervals for repetitive inspections, updating the inspection and repair requirements accordingly. The directive retains the core inspection and repair procedures but clarifies compliance timelines and affected aircraft models.
Why It Matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition that could lead to disconnection of the thrust reverser unit from the engine, risking damage to the engine, aircraft structure, and possible injury on the ground. Operators and maintenance organizations must comply to prevent structural failures and ensure flight safety. Compliance with the AD is mandatory to maintain the aircraft's airworthiness certificate.
What To Do
Operators must perform special detailed inspections (conductivity tests) of each thrust reverser lower beam within specified compliance times, not exceeding 3,300 flight cycles or 48 months since installation. If damage exceeding specified limits is found, the affected beam must be replaced before the next flight. Inspections must continue at intervals defined by the AD, and any installed beam must meet the compliance criteria or pass an inspection before installation.
