The Civil Aviation Safety Authority decided this old safety requirement is no longer necessary because it wasn't based on manufacturer guidance and is now considered obsolete.\n\n**Who is affected:** Owners and operators of Meta Sokol L.40 series aeroplanes (a Czechoslovakian aircraft type)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-l-40-7-amdt-1-landing-gear-aural-warning-modification-cancelled","history":"/api/acts/ad-l-40-7-amdt-1-landing-gear-aural-warning-modification-cancelled/history","analysis":"/api/acts/ad-l-40-7-amdt-1-landing-gear-aural-warning-modification-cancelled/analysis","conflicts":"/api/acts/ad-l-40-7-amdt-1-landing-gear-aural-warning-modification-cancelled/conflicts","importantCases":"/api/acts/ad-l-40-7-amdt-1-landing-gear-aural-warning-modification-cancelled/important-cases","documents":"/api/acts/ad-l-40-7-amdt-1-landing-gear-aural-warning-modification-cancelled/documents"}}
