Investigators have called off their search for missing parts of an A380 superjumbo that fell off when an engine disintegrated in flight earlier this month.

The Australian Transport Safety Bureau said Wednesday that significant parts of the turbine disc believed to be at the center of the engine failure have not been recovered.

One of four Rolls-Royce Trent 900 engines on the Qantas A380 blew apart on Nov. 4 shortly after it took off from Singapore, sending shrapnel through a wing and scattering debris across Indonesia's Batam island.

Investigators have been combing Batam looking for clues but say thick jungle was hampering their search.

The agency said it has now ended the search, but that anybody who finds parts that might be from the plane should contact police.
