This involves replacing the existing mixture control cable with an improved design to prevent mechanical failure.\n\n**When it must be done:**\nWithin the next 100 flight hours after 12 May 1969.\n\n**Why it matters:**\nThe mixture control regulates the fuel-to-air ratio in the engine. A faulty cable assembly could cause engine power loss or failure during critical low-altitude agricultural operations, posing significant safety risks to the pilot and people on the ground."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-188-12-mixture-control-cable-assembly","history":"/api/acts/ad-cessna-188-12-mixture-control-cable-assembly/history","analysis":"/api/acts/ad-cessna-188-12-mixture-control-cable-assembly/analysis","conflicts":"/api/acts/ad-cessna-188-12-mixture-control-cable-assembly/conflicts","importantCases":"/api/acts/ad-cessna-188-12-mixture-control-cable-assembly/important-cases","documents":"/api/acts/ad-cessna-188-12-mixture-control-cable-assembly/documents"}}
