The directive itself doesn't spell out the steps—it points to that external document for the actual inspection or modification process.\n\n**Why it matters:** This ensures potentially faulty elevator components are identified and fixed or removed before they can cause flight control problems."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-205-33-synchronised-elevator-inspection-modification-and-retirement","history":"/api/acts/ad-bell-205-33-synchronised-elevator-inspection-modification-and-retirement/history","analysis":"/api/acts/ad-bell-205-33-synchronised-elevator-inspection-modification-and-retirement/analysis","conflicts":"/api/acts/ad-bell-205-33-synchronised-elevator-inspection-modification-and-retirement/conflicts","importantCases":"/api/acts/ad-bell-205-33-synchronised-elevator-inspection-modification-and-retirement/important-cases","documents":"/api/acts/ad-bell-205-33-synchronised-elevator-inspection-modification-and-retirement/documents"}}
