The old rule required owners to inspect and modify their turbocharger oil scavenge reservoir and lower engine cowl in accordance with a specific Piper service bulletin. As of 9 April 2009, that requirement is dead and buried—owners no longer need to perform these checks or modifications.\n\n**Who it affects**\nOwners and operators of Piper PA-46 (Malibu) series aeroplanes who were previously subject to Directive AD/PA-46/8.\n\n**Why it matters**\nThis removes a maintenance obligation that had been in place since 1985. If you were tracking compliance with the old turbocharger inspection rule, you can stop—you're off the hook."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-46-8-turbocharger-oil-scavenge-reservoir-inspection-modification-and-lower-cowl-modification-c","history":"/api/acts/ad-pa-46-8-turbocharger-oil-scavenge-reservoir-inspection-modification-and-lower-cowl-modification-c/history","analysis":"/api/acts/ad-pa-46-8-turbocharger-oil-scavenge-reservoir-inspection-modification-and-lower-cowl-modification-c/analysis","conflicts":"/api/acts/ad-pa-46-8-turbocharger-oil-scavenge-reservoir-inspection-modification-and-lower-cowl-modification-c/conflicts","importantCases":"/api/acts/ad-pa-46-8-turbocharger-oil-scavenge-reservoir-inspection-modification-and-lower-cowl-modification-c/important-cases","documents":"/api/acts/ad-pa-46-8-turbocharger-oil-scavenge-reservoir-inspection-modification-and-lower-cowl-modification-c/documents"}}
