If wear was found, a permanent modification had to be installed.\n\n**Why it's being scrapped**: More than 40 years have passed. The regulator confirms that every affected aircraft would have been inspected and modified decades ago. Since the safety risk has been eliminated across the entire fleet, the rule is now redundant.\n\n**Who is affected**: Owners and operators of Schweizer (Grumman) G-164 series aircraft — though practically, no action is required because the requirement no longer exists."}},"importantCases":[],"_links":{"self":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection-cancelled","history":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection-cancelled/history","analysis":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection-cancelled/analysis","conflicts":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection-cancelled/important-cases","documents":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection-cancelled/documents"}}
