They address identified unsafe conditions in aircraft. Operating an aircraft without complying with an AD is illegal and poses safety risks (in this case, likely related to preventing ice formation in the engine intake system)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-6-air-intake-heater-installation","history":"/api/acts/ad-cessna-310-6-air-intake-heater-installation/history","analysis":"/api/acts/ad-cessna-310-6-air-intake-heater-installation/analysis","conflicts":"/api/acts/ad-cessna-310-6-air-intake-heater-installation/conflicts","importantCases":"/api/acts/ad-cessna-310-6-air-intake-heater-installation/important-cases","documents":"/api/acts/ad-cessna-310-6-air-intake-heater-installation/documents"}}
