This \"binding\" could lock the elevator in an upward position, preventing the pilot from pushing the nose down—a potentially catastrophic loss of control situation."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-46-2-interface-of-elevator-to-horizontal-stabiliser-inspection-and-modification","history":"/api/acts/ad-pa-46-2-interface-of-elevator-to-horizontal-stabiliser-inspection-and-modification/history","analysis":"/api/acts/ad-pa-46-2-interface-of-elevator-to-horizontal-stabiliser-inspection-and-modification/analysis","conflicts":"/api/acts/ad-pa-46-2-interface-of-elevator-to-horizontal-stabiliser-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-pa-46-2-interface-of-elevator-to-horizontal-stabiliser-inspection-and-modification/important-cases","documents":"/api/acts/ad-pa-46-2-interface-of-elevator-to-horizontal-stabiliser-inspection-and-modification/documents"}}
