CANCELLED: Engine — Power Turbine Wheels — Replacement
Summary
EASA Airworthiness Directive 2018-0044-CN is a cancellation notice issued by the European Union Aviation Safety Agency concerning SAFRAN Helicopter Engines ARRIUS 2 series engines. This document cancels the previous AD 2018-0044 which mandated replacement of certain power turbine wheels due to a risk of blade rupture. The affected engines include ARRIUS 2B1, 2B1A, 2B2, 2G1, 2K1, and 2K2 models.
What Changed
EASA Airworthiness Directive 2018-0044-CN officially cancels the earlier AD 2018-0044 issued in February 2018. The cancellation follows confirmation from SAFRAN that all affected power turbine wheels have been inspected and repaired as necessary, eliminating the unsafe condition. No further mandatory actions or replacements are required under this cancellation notice.
Why It Matters
This cancellation is important for aviation professionals as it confirms that the previously identified risk of power turbine wheel blade rupture in ARRIUS 2 engines has been fully addressed. Operators and maintenance organizations can now consider the unsafe condition resolved, reducing the need for ongoing inspections or part replacements related to this issue. Compliance teams can update their records to reflect the cancellation and avoid unnecessary operational disruptions.
What To Do
Affected stakeholders do not need to take any further action as EASA AD 2018-0044-CN removes the previous requirement to replace or inspect the specified power turbine wheels. Operators should ensure that all affected parts have been inspected or repaired as per SAFRAN's instructions and maintain documentation accordingly.
