This prevents dangerous leaks, chafing, or line failures that could cause engine damage or fire.\n\n**Who it affects**\nAnyone operating aircraft fitted with Artouste 111B engines (commonly used in certain helicopters and light aircraft).\n\n**Compliance deadline**\nThe work had to be completed before **30 April 1974** (note: this is a historical directive).\n\n**How to comply**\nFollow the technical instructions in either:\n* **Turbomeca Service Bulletin No. 79.218.0050**, or\n* Alternative directive **AD/TURB-T/7**\n\n**Why it matters**\nUnsecured or worn oil and fuel lines can fracture due to vibration or heat, leading to catastrophic engine failure, in-flight fire, or forced landings."}},"importantCases":[],"_links":{"self":"/api/acts/ad-artouste-2-oil-and-fuel-lines-replacement-and-support","history":"/api/acts/ad-artouste-2-oil-and-fuel-lines-replacement-and-support/history","analysis":"/api/acts/ad-artouste-2-oil-and-fuel-lines-replacement-and-support/analysis","conflicts":"/api/acts/ad-artouste-2-oil-and-fuel-lines-replacement-and-support/conflicts","importantCases":"/api/acts/ad-artouste-2-oil-and-fuel-lines-replacement-and-support/important-cases","documents":"/api/acts/ad-artouste-2-oil-and-fuel-lines-replacement-and-support/documents"}}
