What happened
The incident involved a seaplane registered as Capella, which was operating an international scheduled flight for Qantas. While maneuvering within the harbor of Batavia (Jakarta), the aircraft collided with an unidentified floating object during its taxiing phase for takeoff.
Following the impact, the pilot aborted the departure procedure and returned to the harbor area. The collision caused the seaplane to partially sink. All eight occupants on board managed to evacuate the aircraft safely without reported injuries. Due to the extent of the water damage and structural compromise, the float plane was declared damaged beyond repair.
Findings
