The exact technical procedure is contained in Cessna Service Letter SE76-3.\n\n**Who it affects:**\nOwners and operators of Cessna 207 aeroplanes within the specified serial number range.\n\n**Why it matters:**\nThe directive addresses a potential safety defect that could cause the rudder trim chain to fail, potentially compromising the pilot's ability to control the aircraft's direction.\n\n**Compliance requirement:**\nThe maintenance must be completed within 100 hours of flight time after 31 May 1976."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-207-11-rudder-trim-chain","history":"/api/acts/ad-cessna-207-11-rudder-trim-chain/history","analysis":"/api/acts/ad-cessna-207-11-rudder-trim-chain/analysis","conflicts":"/api/acts/ad-cessna-207-11-rudder-trim-chain/conflicts","importantCases":"/api/acts/ad-cessna-207-11-rudder-trim-chain/important-cases","documents":"/api/acts/ad-cessna-207-11-rudder-trim-chain/documents"}}
