The regulator decided this rule—originally a unique Australian requirement not based on manufacturer guidance—was no longer necessary for airworthiness. Your emergency fuel pumps still need to work, but CASA won't dictate the exact maintenance interval anymore."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-110-amdt-3-emergency-electrical-fuel-pumps-cancelled","history":"/api/acts/ad-pa-31-110-amdt-3-emergency-electrical-fuel-pumps-cancelled/history","analysis":"/api/acts/ad-pa-31-110-amdt-3-emergency-electrical-fuel-pumps-cancelled/analysis","conflicts":"/api/acts/ad-pa-31-110-amdt-3-emergency-electrical-fuel-pumps-cancelled/conflicts","importantCases":"/api/acts/ad-pa-31-110-amdt-3-emergency-electrical-fuel-pumps-cancelled/important-cases","documents":"/api/acts/ad-pa-31-110-amdt-3-emergency-electrical-fuel-pumps-cancelled/documents"}}
