The safety requirements are now covered by a general directive (AD/GENERAL/4) instead of this aircraft-specific rule.\n\n**Who it affects:** Owners and operators of Cessna 400 series aircraft (though since it's a cancellation, it removes obligations rather than adding them).\n\n**When it takes effect:** The cancellation takes effect on 28 August 2008."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-400-31-amdt-1-placards-and-cabin-fittings-cancelled","history":"/api/acts/ad-cessna-400-31-amdt-1-placards-and-cabin-fittings-cancelled/history","analysis":"/api/acts/ad-cessna-400-31-amdt-1-placards-and-cabin-fittings-cancelled/analysis","conflicts":"/api/acts/ad-cessna-400-31-amdt-1-placards-and-cabin-fittings-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-400-31-amdt-1-placards-and-cabin-fittings-cancelled/important-cases","documents":"/api/acts/ad-cessna-400-31-amdt-1-placards-and-cabin-fittings-cancelled/documents"}}
