As of 7 May 2009, that requirement no longer applies.\n\n**Who it affects:** Owners and operators of Robinson R22 series helicopters who were previously required to comply with this specific maintenance directive.\n\n**Why it matters:** If you were tracking or scheduling compliance with this washer installation rule, you can disregard it. The Civil Aviation Safety Authority (CASA) has removed this regulatory requirement because it is no longer necessary for safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-r22-8-control-systems-safety-washers-installation-cancelled","history":"/api/acts/ad-r22-8-control-systems-safety-washers-installation-cancelled/history","analysis":"/api/acts/ad-r22-8-control-systems-safety-washers-installation-cancelled/analysis","conflicts":"/api/acts/ad-r22-8-control-systems-safety-washers-installation-cancelled/conflicts","importantCases":"/api/acts/ad-r22-8-control-systems-safety-washers-installation-cancelled/important-cases","documents":"/api/acts/ad-r22-8-control-systems-safety-washers-installation-cancelled/documents"}}
