The first check is within 50 hours' flight after 9 June 1971 and must be repeated every 50 hours.  \n\nThe rule addresses heat-exchanger cracks that can cause exhaust leaks, carbon monoxide into the cabin, or engine damage, so regular inspections reduce those serious safety risks."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-210-16-exhaust-manifold-heat-exchanger-inspection","history":"/api/acts/ad-cessna-210-16-exhaust-manifold-heat-exchanger-inspection/history","analysis":"/api/acts/ad-cessna-210-16-exhaust-manifold-heat-exchanger-inspection/analysis","conflicts":"/api/acts/ad-cessna-210-16-exhaust-manifold-heat-exchanger-inspection/conflicts","importantCases":"/api/acts/ad-cessna-210-16-exhaust-manifold-heat-exchanger-inspection/important-cases","documents":"/api/acts/ad-cessna-210-16-exhaust-manifold-heat-exchanger-inspection/documents"}}
