The Civil Aviation Safety Authority (CASA) determined that every affected aircraft would have been inspected and fixed decades ago, so the ongoing requirement serves no purpose.\n\n**What happens now:** As of 30 July 2009, owners and operators of Dornier DO-27 aircraft no longer need to comply with this specific maintenance rule. It removes a compliance burden for what is likely a very small fleet of historic aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection-cancelled","history":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection-cancelled/history","analysis":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection-cancelled/analysis","conflicts":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection-cancelled/important-cases","documents":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection-cancelled/documents"}}
