A Sunstate Airlines de Havilland Dash 8-400 on behalf of Qantas, registration VH-LQM performing flight QF-2130 from Melbourne,VI to Canberra,AC (Australia) with 74 passengers and 4 crew, was descending through 7000 feet on approach to Canberra when the aircraft encountered severe turbulence. The aircraft continued for a safe landing on Canberra's runway 35 about 7 minutes later.

The Australian TSB reported two cabin crew and a passenger received minor injuries as result of the turbulence encounter. An investigation has been opened.

On Jan 17th 2017 the ATSB released their final report releasing following findings:

- The severe turbulence incident was probably an encounter with mountain wave activity in the lee-side of the Brindabella Ranges.

- The captain was probably insufficiently restrained by their crotch strap to prevent them striking their head during the encounter with turbulence.

- The flight crew were prepared for the risk of an encounter with severe turbulence during the descent and approach to Canberra.

The ATSB reported that weather forecasts received by the crew indicated severe turbulence activity during the descent and approach to Canberra.

Enroute at FL210 the captain, pilot flying, instructed cabin crew to prepare the cabin for landing several minutes prior to reaching the top of descent. The approach remained smooth, hence the crew waited with activating the fasten seat belt signs until descending through FL130.

The ATSB then wrote:

Between waypoints GOMAN and HONEY, the aircraft descended below FL 110 and the PF reduced the aircraft speed to 210 kt, which is the best speed for turbulence penetration. The PM estimated that the tailwind component reduced from about 70 kt to about 40 kt after the descent below FL 110. At this point, the aircraft was tracking about 060° and passing in and out of cloud over the Brindabella Ranges, which has ridgelines orientated north-south to the south-west of Canberra.

During the descent, the flight crew did not observe any weather radar indications of potential turbulence or visible indications from the shape or movement of the clouds. Between waypoints HONEY and DALEY at about 7,000 ft AMSL, while passing through a small cloud, the aircraft dropped abruptly. The flight crew reported that everything in the flight deck became airborne, the autopilot disengaged and the PF struck the left side of their head on the overhead air-vent and light, which dislodged their headset. The captain handed control over to the first officer while they refitted their headset and re-established communications, then resumed their flying pilot role and reset the auto-pilot.

The flight crew continued the approach to land at Canberra without further incident and notified Canberra air traffic control of their severe turbulence encounter on the approach. After the aircraft landed, the PM contacted the cabin crew to check if there were any cabin injures to report. The cabin crew indicated they were uninjured and made a public address to the passengers to check for injuries. The PM then called their company to inform them the aircraft was unserviceable after a severe turbulence incident, and also noticed the captain’s minor injuries.

During the disembarkation of the passengers, the cabin crew informed the first officer that one passenger had hit their head on the overhead baggage locker. The first officer then asked a company ground agent to contact the emergency services so the passenger could be checked. However, the passenger declined treatment. The emergency services arrived and checked the captain. The captain was then advised by the company to visit a doctor where they were diagnosed with minor injuries.

The ATSB reported there was one minor injury, the captain of the flight.
