Because that deadline passed decades ago and the modification is no longer relevant to current aviation safety, the Civil Aviation Safety Authority has formally cancelled the directive as of **25 September 2008**. This removes any lingering administrative obligation and clears the regulatory record."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-2-rudder-trim-installation-modification-cancelled","history":"/api/acts/ad-pa-32-2-rudder-trim-installation-modification-cancelled/history","analysis":"/api/acts/ad-pa-32-2-rudder-trim-installation-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-32-2-rudder-trim-installation-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-32-2-rudder-trim-installation-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-32-2-rudder-trim-installation-modification-cancelled/documents"}}
