What happened
The aircraft had been grounded in Jambi for several days due to technical issues. During a subsequent operation involving combat with Dutch forces, the seaplane took off from the surface of the Batang Hari River. Shortly after leaving the water, the aircraft stalled and crashed back into the river, where it sank. Both individuals on board were killed in the incident.
Findings
The accident occurred while the crew was actively engaged in combat operations against Dutch forces. The specific technical problems that had previously grounded the aircraft are not detailed in the available records, but the immediate cause of the crash was a stall shortly after takeoff.
