This is a safety fix to prevent potential fuel system failures.\n\n**Who it affects:**\n- Owners and operators of specific Bell 206A helicopters\n- Only applies to serial numbers: 4–20, 22–48, 50–56, 59, 61, and 63\n- Covers both Bell Helicopter Textron Canada (BHTC) and Agusta Bell 206 series models\n\n**What must be done:**\nThe wiring modification must be completed following Bell Service Letter No. 206A-21 Revision A.\n\n**Deadline:**\nBefore 1 September 1971.\n\n**Why it matters:**\nAirworthiness Directives are legally binding. If you don't comply, you cannot fly the aircraft. This particular directive addresses a specific wiring issue that could affect fuel pump operation — critical for helicopter safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-206-1-fuel-booster-pump-wiring-modification","history":"/api/acts/ad-bell-206-1-fuel-booster-pump-wiring-modification/history","analysis":"/api/acts/ad-bell-206-1-fuel-booster-pump-wiring-modification/analysis","conflicts":"/api/acts/ad-bell-206-1-fuel-booster-pump-wiring-modification/conflicts","importantCases":"/api/acts/ad-bell-206-1-fuel-booster-pump-wiring-modification/important-cases","documents":"/api/acts/ad-bell-206-1-fuel-booster-pump-wiring-modification/documents"}}
