The Sukhoi super jet 100, carrying Russian businessmen and officials of the Russian embassy in Jakarta, lost contact during a promotion flight, Indonesian transport ministry spokesman Bambang Ervan told Xinhua.
Some Indonesians were also on board, a military spokesman said.
The plane took off from Indonesian airbase Halim Perdana Kusuma in East Jakarta. It lost contact at 2.25 p.m. while trying to descend from 10,000 feet to 6,000 feet near a small airport in Bogor, said Ervan.
He said there was no report of bad weather.
