Owners and operators must install the lower elevator cable assembly with the turnbuckle (a device used to adjust cable tension) positioned at the forward end of the assembly.\n\n**Who it affects:** Owners and operators of Meta Sokol L.40 series aeroplanes.\n\n**Why it matters:** The elevator controls the aircraft's pitch (up and down movement). Improper installation of control cables can lead to mechanical failure or loss of control during flight. This directive ensures a critical safety modification is completed to maintain airworthiness and prevent potential accidents."}},"importantCases":[],"_links":{"self":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification","history":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification/history","analysis":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification/analysis","conflicts":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification/conflicts","importantCases":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification/important-cases","documents":"/api/acts/ad-l-40-6-amdt-1-elevator-control-system-modification/documents"}}
