The Australian Transport Safety Bureau (ATSB) has released a preliminary report from its ongoing investigation into a fatal accident involving a Robinson R44 helicopter conducting aerial spraying operations on a farm near Boorowa last December.
Before the 4 December accident, the pilot, a New Zealand national, had completed 10 herbicide spraying runs over paddocks, each lasting about 10 minutes.
When the helicopter did not return 15 minutes after starting the 11th run, and the pilot could not be contacted via radio, a search was instigated.
The wreckage of the helicopter was eventually discovered in a steep gully towards the southern end of the spray area.
Although the seriously injured pilot had managed to free herself from the wreckage, she succumbed to her injuries shortly afterwards.
Director Transport Safety Kerri Hughes said ATSB transport safety investigators’ inspection of the wreckage so far had not identified any evidence of pre-impact structural or mechanical defects with the helicopter.
She said the helicopter’s fuel system was found to hold about 55 litres of fuel, which was visibly clear of contaminants and tested negative to the presence of water, and external examination of the engine did not identify any defects.
ATSB examination of the site identified a tree with broken branches prior to the first items in the debris trail, which included the helicopter’s stabiliser assembly and right-side spray boom.
“There were two ground scars, consistent with landing gear skids, with the majority of the wreckage coming to rest in a gully,” she said.
“As the investigation progresses, ATSB investigators will review and examine witness accounts, recorded data, the wreckage, helicopter documentation, operational records, as well as the pilot’s medical records, qualifications and experience,” Ms Hughes said.
The ATSB will release a final report, which will detail the ATSB’s analysis and findings, at the conclusion of the investigation.
“However, should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate and timely safety action can be taken,” Ms Hughes said.
