On 4 January 2006 at approximately 17:53 Western Standard Time, the pilot of a Eurocopter France AS 350D helicopter, registered VH-KVN, experienced a control problem and the helicopter impacted the ground in a right roll attitude. All occupants escaped with minor injuries. The helicopter was chartered to undertake the establishment and the subsequent recovery of electronic survey markers through the Pilbara area of Western Australia.

It was reported that during an approach to Browns Island, a warning horn activated, and that the pilot carried out a normal landing. The horn provided an audible warning of a number of system parameters including rotor speed and hydraulic pressure. On landing, the pilot noted that the ‘Hydraulic Caption Warning’ segment on the central warning panel was also illuminated. After a visual inspection of the hydraulic pump and its drive belt, a functional check of the hydraulic system and discussion with the senior base engineer in Karratha, the pilot elected to continue to Port Hedland, 3 nautical miles to the east.

It was reported that soon after commencement of forward flight, the aircraft yawed to the left and completed about two and a half to three and a half rotations to the right. The pilot reported that he disengaged the collective mounted hydraulic switch, but the helicopter kept rotating to the right and impacted the ground.
