A defective valve could prevent the flotation gear from deploying, risking the aircraft and occupants sinking.\n\n**How to comply:**\nFollow the inspection procedures in Bell Service Bulletin 206-21 Rev. 'A' (or Agusta Service Bulletin BT206-53 Rev. A for Agusta models)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-206-36-amdt-1-emergency-flotation-solenoid-valve-inspection","history":"/api/acts/ad-bell-206-36-amdt-1-emergency-flotation-solenoid-valve-inspection/history","analysis":"/api/acts/ad-bell-206-36-amdt-1-emergency-flotation-solenoid-valve-inspection/analysis","conflicts":"/api/acts/ad-bell-206-36-amdt-1-emergency-flotation-solenoid-valve-inspection/conflicts","importantCases":"/api/acts/ad-bell-206-36-amdt-1-emergency-flotation-solenoid-valve-inspection/important-cases","documents":"/api/acts/ad-bell-206-36-amdt-1-emergency-flotation-solenoid-valve-inspection/documents"}}
