The replacement must be an approved fire-resistant fuel line. The original directive required this replacement to be completed before 6 May 1965.\n\n**Who it affects:** Anyone responsible for the airworthiness of Cessna 336 aircraft.\n\n**Why it matters:** This prevents engine fires by ensuring the fuel line near the firewall can withstand high heat and flames, rather than using a standard fuel line that could fail in a fire."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-336-1-fuel-line-replacement","history":"/api/acts/ad-cessna-336-1-fuel-line-replacement/history","analysis":"/api/acts/ad-cessna-336-1-fuel-line-replacement/analysis","conflicts":"/api/acts/ad-cessna-336-1-fuel-line-replacement/conflicts","importantCases":"/api/acts/ad-cessna-336-1-fuel-line-replacement/important-cases","documents":"/api/acts/ad-cessna-336-1-fuel-line-replacement/documents"}}
