The cancellation took effect on **7 May 2009**.\n- **Who is affected:** Owners and operators of Robinson R22 series helicopters who were still subject to the original directive.\n\n**Why it matters:**\nOperators no longer need to perform this specific modification to stay compliant with Australian aviation safety regulations.
