This could cause the lines to rub against each other (chafe), potentially causing fuel leaks or fire hazards.\n- **Required action:** Inspect the fuel line and, if necessary, re-route and clamp it to ensure adequate clearance from the vapour return line.\n- **Deadline:** Must be completed within 100 hours of flight time after 29 May 1970.\n\n**Why it matters:** This prevents dangerous fuel leaks that could lead to engine failure or fire in flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-23-fuel-line-inspection","history":"/api/acts/ad-cessna-310-23-fuel-line-inspection/history","analysis":"/api/acts/ad-cessna-310-23-fuel-line-inspection/analysis","conflicts":"/api/acts/ad-cessna-310-23-fuel-line-inspection/conflicts","importantCases":"/api/acts/ad-cessna-310-23-fuel-line-inspection/important-cases","documents":"/api/acts/ad-cessna-310-23-fuel-line-inspection/documents"}}
