AI-generated summary
Four occupants of a light aircraft (VH-PXD) died when it impacted water in Bass Strait on 29 January 2016 while attempting to fly from Melbourne to King Island in poor weather. All three licensed pilots aboard were aware of deteriorating meteorological conditions unsuitable for Visual Flight Rules (VFR) flight, yet continued departure. The coroner found spatial disorientation was a likely causative factor after the aircraft entered low visibility and cloud. No definitive cause of collision could be established, nor could the pilot-in-command be identified. Key clinical/operational lessons include: VFR pilots have insufficient training to manage inadvertent entry into instrument conditions; decision-making failures occurred despite awareness of poor weather; no regulatory requirement existed to identify the pilot-in-command; and pilots can become pressured to continue flights despite deteriorating conditions. The coroner recommended mandatory SARTIME for VFR water flights and increased instrument flight training requirements.

Clinical conditions
Contributing factors
- Decision to depart and continue flight despite deteriorating weather conditions unsuitable for VFR
- Loss of visual cues and spatial disorientation after entering low visibility and cloud
- Insufficient instrument flying training and recency for VFR pilots to manage inadvertent entry into instrument meteorological conditions
- Lack of pilot-in-command identification requirement in aviation regulations
- Pressures and group dynamics influencing pilot decision-making
- Limited real-time weather information exchange capability between departing aircraft and air traffic control
Coroner's recommendations
- Civil Aviation Safety Authority mandates the use of a SARTIME for all Visual Flight Rules flights over water
- Civil Aviation Safety Authority increase Instrument Flight Rule training and recency requirements for Private Pilot Licence candidates and holders, for further education on the fatal dangers of inadvertent entry into Instrument Meteorological Conditions
