Aircraft owners had to complete this inspection by February 1995.\n\n**Why it is being cancelled:**\nThe Civil Aviation Safety Authority cancelled this rule effective **31 July 2008** because all affected aircraft have now undergone the required inspection. Since the safety check has been completed across the entire fleet, the mandatory requirement is no longer necessary.\n\n**Who this affects:**\nOwners and operators of Piper PA-31 series aircraft no longer need to comply with this specific inspection requirement."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-125-electrical-wiring-and-fuel-line-chafing-cancelled","history":"/api/acts/ad-pa-31-125-electrical-wiring-and-fuel-line-chafing-cancelled/history","analysis":"/api/acts/ad-pa-31-125-electrical-wiring-and-fuel-line-chafing-cancelled/analysis","conflicts":"/api/acts/ad-pa-31-125-electrical-wiring-and-fuel-line-chafing-cancelled/conflicts","importantCases":"/api/acts/ad-pa-31-125-electrical-wiring-and-fuel-line-chafing-cancelled/important-cases","documents":"/api/acts/ad-pa-31-125-electrical-wiring-and-fuel-line-chafing-cancelled/documents"}}
