It requires owners or operators of specific Cessna 210 aircraft to modify their control systems to prevent safety hazards.\n\n**Who it affects:**\nOwners or operators of Cessna 210 aeroplanes with serial numbers between 21059138 to 21059211, and T210-0434 to T210-0454.\n\n**What you must do:**\nModify the aircraft's control systems exactly as instructed in **Cessna Service Letter SE69-28** (a technical manual from the manufacturer).\n\n**When:**\nWithin 100 hours of flying time (\"time in service\") after 29 April 1970.\n\n**Why it matters:**\nAirworthiness Directives are legally enforceable safety orders. Failure to comply means the aircraft cannot be flown legally. This specific directive addresses a safety defect in the control systems of these particular aircraft models."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-210-13-control-systems-modification","history":"/api/acts/ad-cessna-210-13-control-systems-modification/history","analysis":"/api/acts/ad-cessna-210-13-control-systems-modification/analysis","conflicts":"/api/acts/ad-cessna-210-13-control-systems-modification/conflicts","importantCases":"/api/acts/ad-cessna-210-13-control-systems-modification/important-cases","documents":"/api/acts/ad-cessna-210-13-control-systems-modification/documents"}}
