What happened
On the scheduled flight from Wewak Airport to Madang, the flight crew observed a warning light on the cockpit instrument panel indicating a technical malfunction. This alert indicated issues regarding the aircraft's wheel brake antiskid systems and the lift dumper testing mechanism. Due to these complications, the pilot elected to divert the flight to Lae-Nadzab, seeking the advantage of a longer runway and available emergency firefighting services.
Upon landing at Lae-Nadzab, the left main landing gear collapsed. This structural failure caused the pilot to lose control of the aircraft type as it veered toward the left side of the runway. The movement resulted in the plane coming to a stop in a nearby ditch. While the aircraft sustained damage beyond repair, there were 0 fatalities and all 49 occupants were able to evacuate the wreckage without injury.
Findings
- The crew identified technical difficulties with the antiskid and lift dumper systems prior to landing.
- The collapse of the left main gear during the landing phase was the primary factor in the loss of directional control.
