This had to be done before September 1971.\n\n**Why it's cancelled:** The Civil Aviation Safety Authority (CASA) decided this modification is no longer required for airworthiness. The cancellation took effect on **27 August 2009**.\n\n**Who it affects:** Owners and operators of Meta Sokol L.40 series aeroplanes who were previously subject to this requirement."}},"importantCases":[],"_links":{"self":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification-cancelled","history":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification-cancelled/history","analysis":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification-cancelled/analysis","conflicts":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification-cancelled/conflicts","importantCases":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification-cancelled/important-cases","documents":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification-cancelled/documents"}}
