You cannot legally fly the aircraft until this modification is completed. While the directive doesn't specify the exact danger, voltage regulators can overheat or produce electrical sparks; the shield likely prevents fire risks or electrical system failures."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-4-voltage-regulator-shield-installation","history":"/api/acts/ad-cessna-310-4-voltage-regulator-shield-installation/history","analysis":"/api/acts/ad-cessna-310-4-voltage-regulator-shield-installation/analysis","conflicts":"/api/acts/ad-cessna-310-4-voltage-regulator-shield-installation/conflicts","importantCases":"/api/acts/ad-cessna-310-4-voltage-regulator-shield-installation/important-cases","documents":"/api/acts/ad-cessna-310-4-voltage-regulator-shield-installation/documents"}}
