The pushrod is a critical component that connects the pilot's control inputs to the tail surfaces; if it breaks, the pilot cannot control the aircraft's pitch, potentially causing a crash."}},"importantCases":[],"_links":{"self":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection","history":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection/history","analysis":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection/analysis","conflicts":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection/conflicts","importantCases":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection/important-cases","documents":"/api/acts/ad-g164-10-elevator-pushrod-assembly-inspection/documents"}}
