EASA AD 2024-0202R1
Engine Fuel & Control — Fuel Control Unit — Replacement
Summary
EASA Airworthiness Directive 2024-0202R1 is a regulatory update addressing the replacement of fuel control units (FCUs) on SAFRAN ARRIUS 2F engines, commonly installed on Airbus Helicopters EC120 B helicopters. The directive targets specific FCU serial numbers that may have a manufacturing defect leading to uncommanded in-flight engine shutdowns. It mandates inspection, replacement, and prohibits installation of affected FCUs to ensure continued airworthiness.
What Changed
This revision updates the list of affected FCU serial numbers by removing those confirmed not to have the manufacturing defect. It refines the scope of the original AD 2024-0202-E by excluding non-affected parts, thereby focusing compliance requirements on truly impacted components. The compliance instructions and deadlines remain consistent with the original directive.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk that could cause engine failure and subsequent hard landings in single-engine helicopters. Operators and maintenance organizations must ensure affected FCUs are replaced promptly to maintain aircraft safety and regulatory compliance. Failure to comply could lead to operational restrictions and increased risk of accidents.
What To Do
Operators with Group 1 engines containing affected FCUs must replace these parts within 15 flight hours or 30 days after 24 October 2024, following SAFRAN's Mandatory Service Bulletin instructions. Installation of any affected FCU on any engine is prohibited from the same date. Maintenance teams should verify FCU serial numbers against the updated list in Appendix 1 and coordinate with SAFRAN Repair Centres for inspections and repairs as needed.
