This contact can cause a short circuit and potentially start a fire.\n\n**What you must do:**\nFollow the technical instructions in **Beechcraft Service Bulletin 2409** to inspect and correct the wiring issue.\n\n**Who is affected:**\nAll operators of Beechcraft 1900 aircraft listed in the manufacturer's service bulletin.\n\n**Compliance deadline:**\nYou must complete this fix before your aircraft reaches **100 hours of flight time after 14 November 1991**.\n\n**Why this matters:**\nThis prevents electrical fires in the cockpit area, protecting crew and passengers from potential in-flight emergencies."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-1900-5-right-circuit-breaker-wire-bundle-clamp","history":"/api/acts/ad-beech-1900-5-right-circuit-breaker-wire-bundle-clamp/history","analysis":"/api/acts/ad-beech-1900-5-right-circuit-breaker-wire-bundle-clamp/analysis","conflicts":"/api/acts/ad-beech-1900-5-right-circuit-breaker-wire-bundle-clamp/conflicts","importantCases":"/api/acts/ad-beech-1900-5-right-circuit-breaker-wire-bundle-clamp/important-cases","documents":"/api/acts/ad-beech-1900-5-right-circuit-breaker-wire-bundle-clamp/documents"}}
