If a standard (non-fire-resistant) hose fails or leaks near a hot engine, it can ignite and cause an in-flight fire. The firewall helps contain engine fires, but hoses passing through or forward of it need extra protection to prevent fire from spreading into the cabin or fuel system. This directive eliminates a known fire hazard by requiring hoses that can withstand high temperatures without failing.\n\n**When to comply:** Immediately (\"forthwith\" means without delay — as soon as practically possible)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-l200-1-fire-resistant-hose-assemblies-installation","history":"/api/acts/ad-l200-1-fire-resistant-hose-assemblies-installation/history","analysis":"/api/acts/ad-l200-1-fire-resistant-hose-assemblies-installation/analysis","conflicts":"/api/acts/ad-l200-1-fire-resistant-hose-assemblies-installation/conflicts","importantCases":"/api/acts/ad-l200-1-fire-resistant-hose-assemblies-installation/important-cases","documents":"/api/acts/ad-l200-1-fire-resistant-hose-assemblies-installation/documents"}}
