This safety check ensures the hydraulic lines won't fail in flight or during landing, which could cause accidents."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-210-24-hydraulic-line-inspection","history":"/api/acts/ad-cessna-210-24-hydraulic-line-inspection/history","analysis":"/api/acts/ad-cessna-210-24-hydraulic-line-inspection/analysis","conflicts":"/api/acts/ad-cessna-210-24-hydraulic-line-inspection/conflicts","importantCases":"/api/acts/ad-cessna-210-24-hydraulic-line-inspection/important-cases","documents":"/api/acts/ad-cessna-210-24-hydraulic-line-inspection/documents"}}
