It requires an inspection of the **elevator horn assembly** — a component in the tail section that helps control the plane's up-and-down movement (pitch).\n\n**Who it affects:** Anyone operating **FU24 series aircraft** made by Airparts (NZ) Ltd. This includes all models of that series.\n\n**What you must do:**\n* Inspect the elevator horn assembly following the instructions in the manufacturer's **Service Letter No. 1**\n* Complete this inspection within **10 hours of flight time** after 15 January 1971\n\n**Why it matters:** This directive addresses potential defects or wear in a critical flight control component. Failing to inspect could lead to loss of control of the aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-fu24-37-elevator-horn-assembly-inspection","history":"/api/acts/ad-fu24-37-elevator-horn-assembly-inspection/history","analysis":"/api/acts/ad-fu24-37-elevator-horn-assembly-inspection/analysis","conflicts":"/api/acts/ad-fu24-37-elevator-horn-assembly-inspection/conflicts","importantCases":"/api/acts/ad-fu24-37-elevator-horn-assembly-inspection/important-cases","documents":"/api/acts/ad-fu24-37-elevator-horn-assembly-inspection/documents"}}
