| Confidence Rating: |  Accident investigation report completed and information captured |
the Bell 505 helicopter registered VH-VTB was conducting a scenic flight near Double Island, Queensland, with a pilot and 2 passengers on board. About 30 minutes into the flight, the pilot heard 2 brief, loud ‘grinding noises’ and elected to proceed to Cairns Airport.
While over the airfield, the grinding began again and did not stop. After 10-12 seconds, approximately 10 ft off the ground, the pilot heard 2 loud bangs, and the helicopter yawed to the right. In response, the pilot moved the throttle to idle, which stopped the yaw. A run-on landing was performed on the grass short of the assigned helipad. Subsequent inspection of the helicopter revealed that the tail rotor driveshaft had failed.
Contributing factor:
- During landing, the forward fan shaft bearing seized and overheated, resulting in failure of the fan shaft.
