In an aircraft, this could lead to loss of electrical power, battery failure, or even fire - creating serious flight safety risks."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-188-17-alternator-earth-lead","history":"/api/acts/ad-cessna-188-17-alternator-earth-lead/history","analysis":"/api/acts/ad-cessna-188-17-alternator-earth-lead/analysis","conflicts":"/api/acts/ad-cessna-188-17-alternator-earth-lead/conflicts","importantCases":"/api/acts/ad-cessna-188-17-alternator-earth-lead/important-cases","documents":"/api/acts/ad-cessna-188-17-alternator-earth-lead/documents"}}
