What to do
Operators of ARRIUS 2F engines must inspect the rear electrical magnetic plug heads within 15 flight hours or 30 days after 18 January 2018 and continue inspections after each flight until replacement. Affected parts must be replaced within 60 days of the effective date with serviceable components following Safran Helicopter Engines Alert MSBs. Installation of affected parts is prohibited after replacement or from the effective date for unaffected engines.
Summary
EASA Airworthiness Directive 2018-0012-E is an emergency directive addressing Safran Helicopter Engines ARRIUS 2F engines, commonly installed on Airbus Helicopters EC120 B models. It mandates inspection and replacement of electrical magnetic plug heads with part number 9 520 01 154 5 due to flaking cadmium coating caused by manufacturing defects. This directive aims to ensure the reliability of the engine's particle detection system to prevent in-flight engine failures.
What changed
This new directive introduces mandatory repetitive inspections of affected magnetic plug heads and requires their replacement within 60 days as a terminating action. It also prohibits installation of the affected parts on any engine after specified compliance dates. The directive is based on Safran Helicopter Engines Alert Mandatory Service Bulletins providing detailed inspection and replacement procedures.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk that could lead to undetected internal engine failures and potential in-flight shutdowns. Operators and maintenance organizations must comply to maintain airworthiness and avoid forced landings or accidents. Compliance ensures continued reliability of the engine oil system's particle detection capability, safeguarding helicopter operation and occupant safety.
