Alternatively, operators may use a repair scheme developed by Ansett Airlines (reference XB-55-30-1A) as an acceptable substitute.\n\n**Why it matters:** The vertical stabiliser is essential for aircraft control and directional stability. This directive ensures these specific aircraft remain safe to fly by mandating corrective action for potential structural defects in the tail section."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-200-12-amdt-2-vertical-stabiliser","history":"/api/acts/ad-beech-200-12-amdt-2-vertical-stabiliser/history","analysis":"/api/acts/ad-beech-200-12-amdt-2-vertical-stabiliser/analysis","conflicts":"/api/acts/ad-beech-200-12-amdt-2-vertical-stabiliser/conflicts","importantCases":"/api/acts/ad-beech-200-12-amdt-2-vertical-stabiliser/important-cases","documents":"/api/acts/ad-beech-200-12-amdt-2-vertical-stabiliser/documents"}}
