This change aligns Australian requirements with European regulations under the Civil Aviation Safety Regulations.\n\n**Who is affected:**\nOwners and operators of Eurocopter Dauphin (SA 360 and SA 365) series helicopters, as well as maintenance organisations servicing these aircraft.\n\n**When it applies:**\nThe cancellation took effect on **27 November 2009**.
