These particular regulations about aircraft engine pollution were due to sunset (expire) on 1 April 2019. This certificate pushes that expiry date back to 1 April 2021.\n\n**Who it affects:** Airlines, aircraft operators, and the Civil Aviation Safety Authority (CASA), who must continue following the existing emissions rules until April 2021.\n\n**Why it matters:** It prevents a regulatory gap where aircraft emissions would go unregulated while the government decides whether to remake, amend, or scrap the rules. The certificate itself disappears on 2 April 2021, the day after the regulations finally sunset."}},"importantCases":[],"_links":{"self":"/api/acts/legislation-deferral-of-sunsetting-air-navigation-aircraft-engine-emissions-regulations-certificate-","history":"/api/acts/legislation-deferral-of-sunsetting-air-navigation-aircraft-engine-emissions-regulations-certificate-/history","analysis":"/api/acts/legislation-deferral-of-sunsetting-air-navigation-aircraft-engine-emissions-regulations-certificate-/analysis","conflicts":"/api/acts/legislation-deferral-of-sunsetting-air-navigation-aircraft-engine-emissions-regulations-certificate-/conflicts","importantCases":"/api/acts/legislation-deferral-of-sunsetting-air-navigation-aircraft-engine-emissions-regulations-certificate-/important-cases","documents":"/api/acts/legislation-deferral-of-sunsetting-air-navigation-aircraft-engine-emissions-regulations-certificate-/documents"}}
