It required an inspection of the empennage attach brackets.

The original rule was issued in 1976 and required the inspection to be done within 100 hours of flying time after April 1976.\n\n**Who it affects**\nOwners and operators of Mooney M20 series aeroplanes who were previously required to comply with directive AD/M20/22.\n\n**Why it matters**\nThe Civil Aviation Safety Authority has cancelled this rule because all affected aircraft would have completed the required inspections and any necessary repairs decades ago. This removes an outdated compliance burden from aircraft owners while maintaining safety, since the work was already done long ago."}},"importantCases":[],"_links":{"self":"/api/acts/ad-m20-22-amdt-1-empennage-attach-brackets-cancelled","history":"/api/acts/ad-m20-22-amdt-1-empennage-attach-brackets-cancelled/history","analysis":"/api/acts/ad-m20-22-amdt-1-empennage-attach-brackets-cancelled/analysis","conflicts":"/api/acts/ad-m20-22-amdt-1-empennage-attach-brackets-cancelled/conflicts","importantCases":"/api/acts/ad-m20-22-amdt-1-empennage-attach-brackets-cancelled/important-cases","documents":"/api/acts/ad-m20-22-amdt-1-empennage-attach-brackets-cancelled/documents"}}
