What happened
An aircraft operating a community service flight departed Murray Bridge at approximately 0800, heading toward Mount Gambier. While weather forecasts suggested marginal visual meteorological conditions (VMC) with expected improvements, actual observations and SPECI reports indicated that conditions were unsuitable for visual flight rules (VFR) operations. During the flight, the pilot performed weather-related diversions and requested cloud base information via radio.
Upon arrival at Mount Gamb andier, the pilot executed a non-standard, high-risk approach and landed in low visibility. Following a brief stop for passenger loading, the pilot departed Mount Gambier into low-level cloud. Lacking the proficiency required for instrument meteorological conditions (IMC), the pilot likely lost visual cues and experienced spatial disorientation. This led to a loss of aircraft control and a subsequent collision with the terrain. There were 1 fatalities in the accident.
The investigation
The investigation confirmed that the aircraft was mechanically serviceable and no pre-existing medical conditions were found in the pilot's records that contributed to the event. Investigators focused on the decision-making process regarding the pilot's choice to fly in marginal weather. The pilot, who had held his license for approximately four years and lacked an instrument rating, may have misinterpreted communications from other aircraft on the common traffic advisory frequency as an indication that landing was possible.
Findings
- The pilot departed Mount Gambier into low-level cloud without the necessary proficiency for instrument meteorological conditions.
- The loss of visual references likely caused spatial disorientation, leading to the loss of control.
- Angel Flight Australia lacked sufficient risk controls and guidance for pilots performing community service flights.
- There was a lack of oversight regarding the safety benefits of using commercial passenger flights when alternatives were available.
- Regulatory limitations prevented the Civil Aviation Safety Authority from effectively differentiating and managing the specific risks associated with community service operations.
Safety message
- Angel Flight Australia should implement better guidance and controls to address the unique operational risks of community service flights.
- Improved systems are needed to ensure safety-related information is communicated to organizations conducting flights on their behalf.
