This means, in the event of an accident, the restraints cannot provide the important defence to reduce the severity of injuries.”ĭuring the examination of the wreckage at the site, the ATSB identified cracking and material loss visible in the exhaust diffuser area. “Standard upper torso restraints are likely not fit-for-purpose for these operations. “In the majority of helicopters used for vertical reference flying, the pilot often needs to be able to lean out to look below the helicopter to observe the line and load,” Dr Godley said. In Australia, vertical reference flying – when a pilot looks down as well as out to position the helicopter – mainly comprises aerial firefighting, and to a lesser extent, lifting operations.ĭuring the ATSB investigation, it was identified that a notable proportion of pilots conducting vertical reference flying operations are likely not routinely wearing upper torso restraints. “It was virtually certain that this lack of upper torso restraint use resulted in the pilot sustaining serious head injuries when the aircraft collided with the riverbed,” Dr Godley said.
