It requires regular inspections of the exhaust system to prevent dangerous failures.\n\n**Who it affects:** Anyone who owns or operates any model of Piper PA-24 (Comanche) series aeroplanes.\n\n**What you must do:** Inspect the aircraft's exhaust system at least once every 100 hours of flight time (\"time in service\"). The specific steps for the inspection are found in the manufacturer's document referenced as Piper Service Letter No. 324C—you must follow those instructions.\n\n**Why it matters:** Exhaust system failures can lead to carbon monoxide poisoning for passengers or cause engine fires. This rule ensures potential cracks, corrosion, or damage are caught before they become dangerous."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-24-14-amdt-1-exhaust-system-inspection","history":"/api/acts/ad-pa-24-14-amdt-1-exhaust-system-inspection/history","analysis":"/api/acts/ad-pa-24-14-amdt-1-exhaust-system-inspection/analysis","conflicts":"/api/acts/ad-pa-24-14-amdt-1-exhaust-system-inspection/conflicts","importantCases":"/api/acts/ad-pa-24-14-amdt-1-exhaust-system-inspection/important-cases","documents":"/api/acts/ad-pa-24-14-amdt-1-exhaust-system-inspection/documents"}}
