What happened
While performing an approach to Runway 18 at Mount Gambier under poor weather conditions, the aircraft made contact with the runway surface while the landing gear remained in the retracted position. During this sequence, the propellers struck the runway twice. Following these impacts, the pilot elected to execute a go-around.
The investigation
Investigators analyzed the progression of the event and the factors that led to the decision to perform a go-around. The examination focused on the circumstances surrounding the approach and the state of the aircraft's landing gear at the moment of touchdown.
