What happened
The incident involved a twin-engine aircraft operating a mapping mission over the West Kalimantan Region in the Dutch Indies. The flight crew consisted of the pilot and a passenger acting as a photographer. During the operation, one of the engines failed while the aircraft was en route.
In response to the mechanical failure, both occupants attempted to maintain a safe altitude by discarding unnecessary items from the cabin. Despite these efforts, the pilot was unable to sustain the required altitude and initiated a forced landing on a beach located near Ketapang. Upon impact with the ground, the aircraft sustained severe structural damage, losing both wings before coming to rest.
Findings
The official investigation identified engine failure in flight as the primary cause of the accident. The aircraft was declared damaged beyond repair following the event. Both individuals on board remained uninjured.
