Update: 17 January 2020
The investigation into the collision with terrain involving EC130 helicopter, VH-YHS, 19 km SSE Mansfield (ALA), Victoria, on 19 January 2019 is continuing.
The report into the investigation is currently in the ‘Examination and analysis’ phase. During this phase, evidence is reviewed and evaluated to determine its relevance, validity, credibility and relationship to other evidence and to the occurrence.
Once the examination of the evidence is complete, the investigation team will test a series of hypotheses to arrive at a number of safety factors that could have contributed to the transport safety occurrence or issue, or otherwise increased safety risk.
The investigation team then convenes a Safety Factor Review with ATSB management. This is a rigorous internal review of the progress of the investigation, its preliminary findings and focus. The Safety Factor Review involves the investigation team presenting their evidence and analysis to reach consensus on the investigation findings. Once consensus is achieved, the report drafting phase of the investigation can begin.
ATSB investigators have so far gathered and analysed information from numerous sources including:
- The pilot in command
- Examination of the wreckage
- Images and video recording of the wreckage
- The manufacturer of the helicopter
- An accredited representative from the State of the manufacturer.
The ATSB is investigating the collision with terrain of an EC130 helicopter, registered VH-YHS, 19 km SSE Mansfield (ALA), Victoria, on 19 January 2019.
The pilot reported that during the initial climb at about 3 m, the helicopter began to yaw and roll to the left at an increasing rate. The pilot then initiated a landing during which the helicopter rolled over. The helicopter was substantially damaged but no one was injured.
As part of the investigation, the ATSB will interview the pilot and obtain other relevant evidence and information.
A report will be released at the conclusion of the investigation.
Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate action can be taken.
