| Background: | Eurocopter has advised the European Aviation Safety Agency (EASA) of a report of an in flight incident which led to the inflation of the emergency floatation gear and the activation of various warnings. |
| Investigations have revealed that a screw that secures the RH lower centre fairing interfered with an electrical harness and caused several short circuits, resulting in the inflation of the emergency floatation gear. |
