This work must be finished within **100 hours of flying time** after 17 March 1969.\n\n**Why it matters:** This directive fixes a known safety defect that could affect engine performance or cause failure. These instructions are legally binding—aircraft cannot fly legally unless they comply."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-188-10-amdt-1-carburettor-air-box-shaft","history":"/api/acts/ad-cessna-188-10-amdt-1-carburettor-air-box-shaft/history","analysis":"/api/acts/ad-cessna-188-10-amdt-1-carburettor-air-box-shaft/analysis","conflicts":"/api/acts/ad-cessna-188-10-amdt-1-carburettor-air-box-shaft/conflicts","importantCases":"/api/acts/ad-cessna-188-10-amdt-1-carburettor-air-box-shaft/important-cases","documents":"/api/acts/ad-cessna-188-10-amdt-1-carburettor-air-box-shaft/documents"}}
