Summary
EASA Airworthiness Directive 2019-0247-E is an emergency directive addressing SAFRAN HELICOPTER ENGINES MAKILA 2A and 2A1 engines installed on helicopters such as the Airbus Helicopters EC 225 LP. It mandates the replacement of Module 01 26-tooth bevel gears with specific part numbers and serial numbers due to a manufacturing quality issue causing gear tooth rupture. The directive aims to prevent engine in-flight shutdowns and potential loss of helicopter power.
What Changed
This new emergency airworthiness directive introduces mandatory replacement of affected Module 01 bevel gears on MAKILA 2 engines. It prohibits installation of the affected parts and engines containing them and requires repetitive inspections for certain helicopters until replacement is completed. The directive also provides detailed compliance timelines and corrective actions.
Why It Matters
This directive is critical for aviation professionals to ensure continued airworthiness and safe operation of helicopters equipped with MAKILA 2 engines. Operators and maintenance organizations must act promptly to avoid engine failures that could lead to loss of control or power. Compliance is essential to meet regulatory requirements and maintain operational safety.
What To Do
Operators must replace affected 26-tooth bevel gears on MAKILA 2A and 2A1 engines according to helicopter grouping: Group 1 helicopters require replacement before the next flight after 8 October 2019, while Group 2 helicopters have up to 100 flight hours or 12 months to comply. Repetitive inspections are required for Group 2 helicopters until replacement. Installation of affected parts or engines is prohibited from the effective date.
