Think of it as a recall notice with legal teeth for aircraft owners.\n\n**Who it hits:** Owners and operators of Piper PA-34-200T Seneca aeroplanes with serial numbers between **34-7570001 and 34-7770369**.\n\n**What you must do:** Inspect and modify the fuel lines according to the technical instructions in **Piper Service Bulletin No. 584**. This law doesn’t describe the actual mechanical steps — it simply orders you to follow that manufacturer document (a technique called 'incorporation by reference').\n\n**Deadline:** Within 100 hours of flying time after 28 February 1978.\n\n**Why it matters:** Fuel line failures can cause engine stoppage or in-flight fires. This directive mandates a specific safety fix for a identified batch of high-risk aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-34-26-fuel-line-inspection-and-modification","history":"/api/acts/ad-pa-34-26-fuel-line-inspection-and-modification/history","analysis":"/api/acts/ad-pa-34-26-fuel-line-inspection-and-modification/analysis","conflicts":"/api/acts/ad-pa-34-26-fuel-line-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-pa-34-26-fuel-line-inspection-and-modification/important-cases","documents":"/api/acts/ad-pa-34-26-fuel-line-inspection-and-modification/documents"}}
