EDWARDS AIR FORCE BASE, Calif. (AP) _ A Navy-leased cargo plane on a test mission from nearby China Lake Naval Air Weapons Station crashed on a runway, killing two of the nine people aboard, officials said.

The seven survivors were taken to an Edwards Air Force Base hospital, then transferred to other hospitals in the area, said China Lake spokesman Steve Boster. Six were in serious condition, he said.

Cathy Partusch, public affairs officer at the naval station, said the plane crashed at 12:30 p.m. Monday. It was carrying civilians and military personnel, she said.

''We don't know if it was trying to land or trying to take off,'' said Air Force Tech. Sgt. Melvin L. Wilson, spokesman at Edwards' Flight Test Center. The cause of the crash was under investigation, he said.

Edwards Air Force Base is in the Mojave Desert about 70 miles north of Los Angeles.
