It applies to owners and operators of **Aero Resources J2 series gyroplanes** (a type of small helicopter-like aircraft).\n\n**What you must do:**\nInstall a visible sign (placard) in the cockpit that clearly states when smoking is prohibited on the aircraft.\n\n**When you must do it:**\nBefore the aircraft can be issued with a **Certificate of Airworthiness** (the official safety certificate required before an aircraft is legally allowed to fly).\n\n**Why this matters:**\nSmoking in aircraft creates fire risks, especially in small cockpits. This directive ensures all J2 gyroplanes have clear warnings to protect passengers and crew, and to meet basic aviation safety standards."}},"importantCases":[],"_links":{"self":"/api/acts/ad-mch-4-smoking-placard-installation","history":"/api/acts/ad-mch-4-smoking-placard-installation/history","analysis":"/api/acts/ad-mch-4-smoking-placard-installation/analysis","conflicts":"/api/acts/ad-mch-4-smoking-placard-installation/conflicts","importantCases":"/api/acts/ad-mch-4-smoking-placard-installation/important-cases","documents":"/api/acts/ad-mch-4-smoking-placard-installation/documents"}}
