A Robinson R66 made a hard landing in the waters of Lake Teletskoye near Iogach, Turochak District, Altai Republic during a night time flight. The pilots got out of the water on their own and called an ambulance. One has an open fracture of the shin and abrasions, the other has multiple small cuts. The helicopter sank completely.
The helicopter was being ferried from the Moscow region to the Altai Republic, where it was to be tested by a new owner. The aircraft did not have a valid airworthiness certificate. The flight plan was submitted under the call sign of another aircraft — R44 (RA-05572).
Conclusion
The aviation accident involving the R66 helicopter (registration RA-06368) occurred as a result of its collision with the water surface of a lake.
Because the aircraft was located in an inaccessible area and there were no objective control data (flight recorders or monitoring systems) available, it was not possible to determine the causes or contributing factors of the accident.
