While the original compliance date dates back to 1969, this amendment ensures the directive remains current and enforceable for these aircraft, which may still be flying today as vintage or working aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-185-14-amdt-1-carburettor-air-box-shaft","history":"/api/acts/ad-cessna-185-14-amdt-1-carburettor-air-box-shaft/history","analysis":"/api/acts/ad-cessna-185-14-amdt-1-carburettor-air-box-shaft/analysis","conflicts":"/api/acts/ad-cessna-185-14-amdt-1-carburettor-air-box-shaft/conflicts","importantCases":"/api/acts/ad-cessna-185-14-amdt-1-carburettor-air-box-shaft/important-cases","documents":"/api/acts/ad-cessna-185-14-amdt-1-carburettor-air-box-shaft/documents"}}
