This was a unique Australian requirement not mandated by the aircraft manufacturer.\n\n**What this does**\nThis amendment **cancels** that inspection requirement entirely as of 25 September 2008. The Civil Aviation Safety Authority reviewed the safety data and determined the mandatory inspections were no longer necessary to maintain airworthiness.\n\n**Why this matters**\nAircraft owners no longer need to pay for this specific inspection during routine maintenance, reducing compliance costs without compromising safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-15-amdt-2-rudder-trim-arm-assembly-cracking-cancelled","history":"/api/acts/ad-pa-32-15-amdt-2-rudder-trim-arm-assembly-cracking-cancelled/history","analysis":"/api/acts/ad-pa-32-15-amdt-2-rudder-trim-arm-assembly-cracking-cancelled/analysis","conflicts":"/api/acts/ad-pa-32-15-amdt-2-rudder-trim-arm-assembly-cracking-cancelled/conflicts","importantCases":"/api/acts/ad-pa-32-15-amdt-2-rudder-trim-arm-assembly-cracking-cancelled/important-cases","documents":"/api/acts/ad-pa-32-15-amdt-2-rudder-trim-arm-assembly-cracking-cancelled/documents"}}
