Think of it like a compulsory recall notice, but for aircraft instead of cars.\n\n**What it requires:** Owners and operators of specific **Beechcraft 65-B80 \"Queen Air\" aeroplanes** (serial numbers LD-441 through LD-490) must modify the **strobe light bonding straps** if their aircraft is fitted with specific Grimes strobe light part numbers (30-0467-1 or 30-0467-3).\n\n**Why it matters:** \"Bonding straps\" are electrical connections that prevent dangerous static electricity buildup and ensure proper grounding. Faulty or inadequate bonding on strobe lights can cause:\n- Electrical interference with navigation or communication systems\n- Fire hazards from arcing or sparking\n- Failure of the anti-collision lights themselves\n\n**Who must act:** Anyone operating the affected aircraft models with the specified serial numbers and strobe light equipment.\n\n**When:** The modification had to be completed within **100 hours of flying time** after 31 January 1975 (this is a historical directive from 1975).\n\n**How to comply:** Follow the technical instructions in **Beechcraft Service Instruction No. 0655-362, Revision 1**."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-43-strobe-light-bonding-straps-modification","history":"/api/acts/ad-beech-65-43-strobe-light-bonding-straps-modification/history","analysis":"/api/acts/ad-beech-65-43-strobe-light-bonding-straps-modification/analysis","conflicts":"/api/acts/ad-beech-65-43-strobe-light-bonding-straps-modification/conflicts","importantCases":"/api/acts/ad-beech-65-43-strobe-light-bonding-straps-modification/important-cases","documents":"/api/acts/ad-beech-65-43-strobe-light-bonding-straps-modification/documents"}}
