This creates a serious risk of losing control of the aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-24-32-amdt-1-stabilator-attachment-bolts-inspection","history":"/api/acts/ad-pa-24-32-amdt-1-stabilator-attachment-bolts-inspection/history","analysis":"/api/acts/ad-pa-24-32-amdt-1-stabilator-attachment-bolts-inspection/analysis","conflicts":"/api/acts/ad-pa-24-32-amdt-1-stabilator-attachment-bolts-inspection/conflicts","importantCases":"/api/acts/ad-pa-24-32-amdt-1-stabilator-attachment-bolts-inspection/important-cases","documents":"/api/acts/ad-pa-24-32-amdt-1-stabilator-attachment-bolts-inspection/documents"}}
