JAKARTA, Indonesia (AP) - An official says air controllers have lost contact with a Russian-made plane carrying 46 people in western Indonesia.

National search agency spokesman Gagah Prakoso says the Sukhoi Superjet-100 was on a demonstration flight Wednesday when it lost contact with authorities near Salak mountain in West Java province.

He says a rescue team has been dispatched to area.

The aircraft took off from Jakarta's Halim Perdanakusuma Airport at 2 p.m. (0700 GMT) and was scheduled to return 50 minutes later.

The civilian plane, developed by the Russian aerospace company Sukhoi in co-operation with Western partners, made its maiden flight in 2008 and is now being demonstrated in the region.
