This directive ensures inspections happen correctly. \"Amendment 1\" simplifies the inspection process compared to the original version, making it easier for mechanics to comply without compromising safety.\n\n**Who must comply:** Anyone operating or maintaining Agusta A109A or A109AII helicopters in Australia."}},"importantCases":[],"_links":{"self":"/api/acts/ad-a109-3-amdt-1-passenger-and-pilots-door-emergency-release-mechanism","history":"/api/acts/ad-a109-3-amdt-1-passenger-and-pilots-door-emergency-release-mechanism/history","analysis":"/api/acts/ad-a109-3-amdt-1-passenger-and-pilots-door-emergency-release-mechanism/analysis","conflicts":"/api/acts/ad-a109-3-amdt-1-passenger-and-pilots-door-emergency-release-mechanism/conflicts","importantCases":"/api/acts/ad-a109-3-amdt-1-passenger-and-pilots-door-emergency-release-mechanism/important-cases","documents":"/api/acts/ad-a109-3-amdt-1-passenger-and-pilots-door-emergency-release-mechanism/documents"}}
