What happened
The incident involved a DH.83 Fox Moth operating out of Port Moresby. The aircraft was carrying one pilot, three passengers, and two sacks of rice as cargo. During the landing phase, the undercarriage failed, causing the airplane to veer off the runway surface. The aircraft subsequently collided with an embankment. All four occupants on board were unhurt in the accident. However, the damage sustained by the airframe was severe enough that it was declared damaged beyond repair and not repaired.
Findings
Investigations indicated that the pilot had limited experience flying this specific type of aircraft, having previously operated primarily DC-3s. The encounter with katabatic winds during the landing approach was cited as a contributing factor to the loss of control.
