You need to follow the instructions in Cessna Service Information Letter SE 80-16 to perform the required actions.\n\n**Why it matters:** Some of these brass turnbuckles have been found with longitudinal cracks (splits running lengthwise) radiating from the end of the component. This could compromise the flight control system and create a serious safety risk.\n\n**When to comply:** The inspection and any necessary repairs must be completed within 100 hours of flight time after 30 April 1980."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-206-31-flying-control-system-turnbuckles","history":"/api/acts/ad-cessna-206-31-flying-control-system-turnbuckles/history","analysis":"/api/acts/ad-cessna-206-31-flying-control-system-turnbuckles/analysis","conflicts":"/api/acts/ad-cessna-206-31-flying-control-system-turnbuckles/conflicts","importantCases":"/api/acts/ad-cessna-206-31-flying-control-system-turnbuckles/important-cases","documents":"/api/acts/ad-cessna-206-31-flying-control-system-turnbuckles/documents"}}
