Because the general rule already covers these cargo containers, the specific ban is redundant and no longer needed.\n\n**Who it affects:** Aircraft operators and maintenance providers who previously had to comply with the specific requirements for these cargo containers.\n\n**Result:** This simplifies the rules by removing a redundant requirement while maintaining safety standards through existing broader regulations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-res-25-seat-mounted-cargo-containers-cancelled","history":"/api/acts/ad-res-25-seat-mounted-cargo-containers-cancelled/history","analysis":"/api/acts/ad-res-25-seat-mounted-cargo-containers-cancelled/analysis","conflicts":"/api/acts/ad-res-25-seat-mounted-cargo-containers-cancelled/conflicts","importantCases":"/api/acts/ad-res-25-seat-mounted-cargo-containers-cancelled/important-cases","documents":"/api/acts/ad-res-25-seat-mounted-cargo-containers-cancelled/documents"}}
