The inspection procedures are detailed in the manufacturer's document, Dornier Technical Bulletin No. 27/1.\n\n**Why it matters:** This prevents potential structural failures in the aircraft's elevator control system—the part that controls the up-and-down movement of the plane—which could cause loss of control during flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection","history":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection/history","analysis":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection/analysis","conflicts":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection/conflicts","importantCases":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection/important-cases","documents":"/api/acts/ad-do-27-3-elevator-hinge-bracket-inspection/documents"}}
