The original rule required this inspection to be completed within 100 hours of flying time after November 1967.\n\n**Why it matters**\nAs of 28 August 2008, aircraft owners no longer need to perform this specific inspection. The Civil Aviation Safety Authority (CASA) determined the inspection is no longer necessary for safety, removing a compliance burden from operators of these older aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection-cancelled","history":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection-cancelled/history","analysis":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection-cancelled/analysis","conflicts":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection-cancelled/important-cases","documents":"/api/acts/ad-pa-23-35-amdt-1-stabiliser-attachment-fittings-inspection-cancelled/documents"}}
