Plain English Summary

1/10 complexity

What this does: This document officially cancels a previous safety rule (Airworthiness Directive AD/R22/18) affecting Robinson R22 helicopters.

The old rule: Previously, owners had to replace a specific part—the "actuator drive screw A506-1"—within 25 flying hours or by August 1983 (whichever came first). This was required due to safety concerns identified in a manufacturer service bulletin (Robinson SB No. 32).

What changed: As of 7 May 2009, helicopter owners no longer need to comply with this specific replacement requirement. The Civil Aviation Safety Authority (CASA) determined the rule was no longer necessary for safety.

Who is affected: Owners and operators of Robinson R22 series helicopters who were previously subject to this maintenance directive.
