Operators must follow the instructions in the manufacturer's **Service Bulletin Issue 7** (a technical repair notice) immediately.\n\n**Who it affects:**\nAnyone who owns or operates an Auster/Beagle A.61 series aeroplane manufactured before August 1947.\n\n**Why it matters:**\nFaulty tail attachment bolts could cause the tail to separate from the aircraft during flight, leading to a crash. This directive ensures these critical bolts are checked and fixed before the aircraft flies again.\n\n**Key terms:**\n- **Service Bulletin (SB):** A technical notice issued by the aircraft manufacturer telling owners how to fix a specific problem.\n- **Forthwith:** Immediately; without delay."}},"importantCases":[],"_links":{"self":"/api/acts/ad-aus-2-tail-attachment-bolts","history":"/api/acts/ad-aus-2-tail-attachment-bolts/history","analysis":"/api/acts/ad-aus-2-tail-attachment-bolts/analysis","conflicts":"/api/acts/ad-aus-2-tail-attachment-bolts/conflicts","importantCases":"/api/acts/ad-aus-2-tail-attachment-bolts/important-cases","documents":"/api/acts/ad-aus-2-tail-attachment-bolts/documents"}}
