This simplifies the rules by removing redundant, aircraft-specific regulations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-nav-3-front-seat-restraint-installations-modification-cancelled","history":"/api/acts/ad-nav-3-front-seat-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-nav-3-front-seat-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-nav-3-front-seat-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-nav-3-front-seat-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-nav-3-front-seat-restraint-installations-modification-cancelled/documents"}}
