It addresses wing wiring chafing that can expose wiring near fuel systems — creating a significant fire/explosion hazard — and therefore requires immediate disconnection of heater power, inspection and corrective action on the wiring, and completion of repairs before restoring power. Power must be disconnected within 10 flight hours of the effective date."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-55-24-fuel-vent-heater-wiring","history":"/api/acts/ad-beech-55-24-fuel-vent-heater-wiring/history","analysis":"/api/acts/ad-beech-55-24-fuel-vent-heater-wiring/analysis","conflicts":"/api/acts/ad-beech-55-24-fuel-vent-heater-wiring/conflicts","importantCases":"/api/acts/ad-beech-55-24-fuel-vent-heater-wiring/important-cases","documents":"/api/acts/ad-beech-55-24-fuel-vent-heater-wiring/documents"}}
