What to do
Operators of ARRIUS 2G1 engines must identify if their engines have affected fuel filter pre-blockage pressure switches and replace them with serviceable parts within 7 months or 300 flight hours from 23 December 2019, whichever occurs first. Installation of affected parts is prohibited after this directive's effective date. Maintenance teams should follow SAFRAN Mandatory Service Bulletin N° 319 73 2856 for replacement instructions.
Summary
EASA Airworthiness Directive 2019-0296 is an airworthiness directive addressing SAFRAN Helicopter Engines ARRIUS 2G1 engines, commonly installed on Kamov Ka-226T helicopters. The directive mandates the replacement of certain fuel filter pre-blockage pressure switches identified by specific part and serial numbers due to potential non-conformities. This AD aims to ensure continued safe operation by preventing uncommanded engine shutdowns caused by fuel filter contamination.
What changed
EASA Airworthiness Directive 2019-0296 introduces a mandatory replacement requirement for affected fuel filter pre-blockage pressure switches on ARRIUS 2G1 engines. It prohibits the installation of any affected parts and requires operators to replace these parts within a specified compliance period. This is a new directive addressing a previously identified unsafe condition.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to uncommanded engine shutdowns and reduced helicopter control. Operators and maintenance organizations must comply to maintain aircraft airworthiness and avoid potential in-flight engine failures. Compliance ensures adherence to European Union aviation safety regulations and prevents operational disruptions.
