AD/ARRIEL/34 - Module M05 - Lubrication Duct - CANCELLED

What this does: This officially cancels an earlier Australian safety rule (Airworthiness Directive 34) that applied to lubrication ducts in Turbomeca Arriel turbine engines—commonly used in helicopters.

Who it affects: Aircraft owners, operators, and maintenance engineers responsible for Turbomeca Arriel series engines.

Why it matters: The Australian safety requirements have been replaced by a European safety directive (EASA AD 2009-0245-E). Instead of following separate Australian rules, affected operators now comply directly with the European regulation. This simplifies compliance by aligning Australian requirements with the engine manufacturer's home jurisdiction (France).
