If these bolts crack or fail, the vertical fin could separate from the aircraft during flight, causing loss of control."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-14-fin-spar-attachment-bolts-inspection","history":"/api/acts/ad-cessna-310-14-fin-spar-attachment-bolts-inspection/history","analysis":"/api/acts/ad-cessna-310-14-fin-spar-attachment-bolts-inspection/analysis","conflicts":"/api/acts/ad-cessna-310-14-fin-spar-attachment-bolts-inspection/conflicts","importantCases":"/api/acts/ad-cessna-310-14-fin-spar-attachment-bolts-inspection/important-cases","documents":"/api/acts/ad-cessna-310-14-fin-spar-attachment-bolts-inspection/documents"}}
