LIMA, Peru (AP) _ Rescuers searched today for survivors of a charter flight that crashed just short of an airfield in Peru's northern jungles with 87 people aboard, most of them oil workers for Los Angeles-based Occidental Petroleum.

No Americans were on board the chartered Boeing 737 that crashed Tuesday night, said Howard Collins, a company spokesman; most of Occidental's employees in the country are Peruvian.

The jet took off from the jungle city of Iquitos, 620 miles northeast of Lima, carrying 79 passengers and eight crew members on a 225-mile flight to the oil camp of Andoas, Occidental said.

It crashed at 9:30 p.m. (10:30 p.m. EDT), about 45 minutes into its flight and three miles shy of Andoas. The area is near the border with Ecuador.

Occidental, working with Peru's air force, made plans to send out search teams at daylight today.
