In one incident, a broken brace was sucked into the engine, causing complete engine failure and potential crash. This directive prevents catastrophic failure by catching metal fatigue before the brace breaks loose."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-205-43-engine-air-inlet-screen-inspection","history":"/api/acts/ad-bell-205-43-engine-air-inlet-screen-inspection/history","analysis":"/api/acts/ad-bell-205-43-engine-air-inlet-screen-inspection/analysis","conflicts":"/api/acts/ad-bell-205-43-engine-air-inlet-screen-inspection/conflicts","importantCases":"/api/acts/ad-bell-205-43-engine-air-inlet-screen-inspection/important-cases","documents":"/api/acts/ad-bell-205-43-engine-air-inlet-screen-inspection/documents"}}
