Taxiing

The twin engine aircraft was standing by at the holding point for takeoff when it was hit by a USN Chance Vought F4U Corsair registered 121834. Its pilot was performing a local training mission. The Navigator was destroyed and one of its pilot was killed while four other occupants were injured. The pilot of the Corsair survived.

While taxiing in the harbor of Port Vila, ready for takeoff, the pilot in command was apparently forced to make an evasive maneuver due to the presence of canoe's crossing his path. Doing so, the seaplane hit coral that punctured the bottom of the fuselage, causing water to penetrate into the aircraft that sank on its nose and was partially submerged. All occupants evacuated safely while the aircraft was written off.
