The inspection had to follow Piper Service Bulletin No. 877.\n\n**What changed**\nAs of **9 April 2009**, aircraft owners and maintenance engineers no longer need to perform this specific inspection. The Civil Aviation Safety Authority (CASA) has determined this safety requirement is no longer necessary, likely because the affected aircraft have aged out of the risk period or alternative safety measures are now in place.\n\n**Who this affects**\nOwners and operators of Piper PA-42 (Cheyenne III) series aircraft registered in Australia."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-42-16-control-column-control-chain-retainer-clips-cancelled","history":"/api/acts/ad-pa-42-16-control-column-control-chain-retainer-clips-cancelled/history","analysis":"/api/acts/ad-pa-42-16-control-column-control-chain-retainer-clips-cancelled/analysis","conflicts":"/api/acts/ad-pa-42-16-control-column-control-chain-retainer-clips-cancelled/conflicts","importantCases":"/api/acts/ad-pa-42-16-control-column-control-chain-retainer-clips-cancelled/important-cases","documents":"/api/acts/ad-pa-42-16-control-column-control-chain-retainer-clips-cancelled/documents"}}
