- The flight crew lost confidence in their flight plan weather forecasts after two missed approaches at Paraburdoo Airport. Without immediate access to actual weather information, they elected to conduct further approaches instead of diverting.
- After the third missed approach, the flight crew had insufficient fuel to divert to a suitable airport and were committed to landing in conditions below their landing minima due to the continuing deteriorating cloud base.
and
- Network Aviation did not provide their flight crew with a diversion decision-making procedure for the circumstances where their flights encountered unforecast weather below landing minima. This increased the risk that their flight crew would not anticipate and be adequately prepared for a diversion. (Safety issue)
- Network Aviation did not include the threat of unforecast weather below landing minima in their controlled flight into terrain risk assessments. This increased the risk that controls required to manage this threat would not be developed, monitored, and reviewed at a management level. (Safety issue)
No suprise we had a serious incident
