The replacement must be an approved fire-resistant line.\n\n**Why it matters:** The original fuel line posed a fire hazard. This directive mandates a safer, fire-resistant replacement to reduce the risk of engine fires.\n\n**Compliance:** The replacement had to be completed before 31 May 1965."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-337-1-fuel-line-replacement","history":"/api/acts/ad-cessna-337-1-fuel-line-replacement/history","analysis":"/api/acts/ad-cessna-337-1-fuel-line-replacement/analysis","conflicts":"/api/acts/ad-cessna-337-1-fuel-line-replacement/conflicts","importantCases":"/api/acts/ad-cessna-337-1-fuel-line-replacement/important-cases","documents":"/api/acts/ad-cessna-337-1-fuel-line-replacement/documents"}}
