These are small, single-engine planes typically used for training and private flying.\n\n**What you must do**\n*   Follow the inspection steps in **American Aviation Service Bulletin No. 133** (a technical guide from the manufacturer)\n*   Complete the inspection within **25 hours of flying time** after 24 April 1973\n\n**Why this matters**\nFaulty fuel lines can leak, causing engine failure or fire. This is a mandatory safety check to keep these aircraft airworthy."}},"importantCases":[],"_links":{"self":"/api/acts/ad-aa-1-11-fuel-pressure-lines-inspection","history":"/api/acts/ad-aa-1-11-fuel-pressure-lines-inspection/history","analysis":"/api/acts/ad-aa-1-11-fuel-pressure-lines-inspection/analysis","conflicts":"/api/acts/ad-aa-1-11-fuel-pressure-lines-inspection/conflicts","importantCases":"/api/acts/ad-aa-1-11-fuel-pressure-lines-inspection/important-cases","documents":"/api/acts/ad-aa-1-11-fuel-pressure-lines-inspection/documents"}}
