During takeoff, the aircraft became airborne but owing to insufficient flying speed, struck the water several times, bouncing severely on each occasion. It finally came to rest adjacent to the mangroves on the south eastern portion of East Arm where it sank due to a damaged hull. There were no casualties but the aircraft was written off.

The four engine aircraft crashed when attempting to land at Fenton Airfield, in the Northern Territory, following a bombing raid on Japanese shipping targets in Timor. The Liberator was out of fuel and losing height rapidly. It was just before midnight and conditions were very hazy and the pilot, Flight Lieutenant Arthur Cambridge, could not see the runway flare path. On his first approach to land, he was too far to the left of the runway. He was advised of this by radio contact with ground control. On his second attempt to land, three of the four fuel pressure gauges dropped to zero and the Liberator swung violently to port. Cambridge ordered the crew to crash positions and with his undercarriage still retracted the Liberator crashed through some trees 3 kilometers from Fenton Airfield and struck the ground in a more or less level attitude. A fire broke out below the flight deck, possibly due to damage to the auxiliary power unit. Two crew members were killed while nine other occupants were rescued.

As the crew failed to make the dawn rendezvous, SAR mission was conducted and eventually suspended three days later as no trace of the aircraft was found.
