The work must follow **Piper Service Bulletin No. 161A** (a manufacturer's official technical instruction).\n\n**Who it affects:** Anyone who owns, operates, or maintains a Piper PA-20 aircraft in Australia.\n\n**Key requirements:**\n- **When to do it:** Within 25 hours of flying time after 31 March 1985, and then again every 100 hours of flying time thereafter.\n- **Why it exists:** After an actual in-flight fire occurred, CASA decided to re-issue safety requirements that had previously been cancelled (under an older directive, AD/PA-20/4).\n- **US connection:** The directive notes that the US Federal Aviation Administration (FAA) has a similar order (AD 57-22-1), suggesting this addresses a known design flaw.\n\n**Why it matters:** In-flight fires can kill. This directive forces proactive maintenance to prevent fuel or electrical fires in a specific aircraft type with a known vulnerability."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-20-14-fire-hazard-prevention-inspection-and-rework","history":"/api/acts/ad-pa-20-14-fire-hazard-prevention-inspection-and-rework/history","analysis":"/api/acts/ad-pa-20-14-fire-hazard-prevention-inspection-and-rework/analysis","conflicts":"/api/acts/ad-pa-20-14-fire-hazard-prevention-inspection-and-rework/conflicts","importantCases":"/api/acts/ad-pa-20-14-fire-hazard-prevention-inspection-and-rework/important-cases","documents":"/api/acts/ad-pa-20-14-fire-hazard-prevention-inspection-and-rework/documents"}}
