This device helps control the aircraft's horizontal tail.\n\n**Specifically, check:**\n*   The nut and washer at the top end for excessive wear\n*   That the part is properly lubricated\n*   That the jack-shaft has only minimal 'end play' (looseness) — just enough to let it rotate freely through its full range of motion\n\n**Why it matters:**\nThis ensures the tail control mechanism operates safely and doesn't fail in flight due to wear or lack of lubrication."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-22-12-tailplane-actuating-jack-inspection","history":"/api/acts/ad-pa-22-12-tailplane-actuating-jack-inspection/history","analysis":"/api/acts/ad-pa-22-12-tailplane-actuating-jack-inspection/analysis","conflicts":"/api/acts/ad-pa-22-12-tailplane-actuating-jack-inspection/conflicts","importantCases":"/api/acts/ad-pa-22-12-tailplane-actuating-jack-inspection/important-cases","documents":"/api/acts/ad-pa-22-12-tailplane-actuating-jack-inspection/documents"}}
