Narrative:
On 7/9/2012, three tourists and a pilot had a lucky escape when a helicopter was forced to make an emergency landing north of Broome. An eyewitness who saw the helicopter in trouble about 11.25am said it landed “really hard” on the road to Coconut Wells about 15km from Broome, snapping the tail on impact.

According to the summary of the official ATSB report into the incident:

"On 7 September 2012 at 0930 Western Standard Time, a Robinson R44 Raven II helicopter registered VH-HYR departed Broome airport, Western Australia on a charter flight to a pearl farm, located north of Broome. On board the helicopter were the pilot and three passengers.

Shortly after departing Broome Airport, the pilot reported that the engine and rotor tachometer were indicating that the engine and rotor revolutions per minute were at the upper limit of the operating range. The pilot also advised that the engine and rotor sounded like it was overspeeding. The pilot switched the governor off and was able to reduce the engine and rotor RPM, however the low RPM light and horn activated. At about 200 feet above ground level and a speed of 60-70 knots, the pilot was unable to re-establish control of the engine RPM and he elected to perform a precautionary landing on a road. The helicopter landed heavily and the main rotor severed the tail boom. All occupants exited the helicopter without injury.

The reason for the accident was not conclusively established. However a malfunction within the governor assembly itself or the right magneto was considered likely.
