EAST HARTFORD, Conn. (AP) _ Jet engine-maker Pratt & Whitney is eliminating 1,700 additional jobs, the vast majority of them from its Connecticut-based manufacturing plants.

The cuts are in addition to the approximately 3,500 jobs the company has been in the process of eliminating since it started a major restructuring and consolidation effort in 1998.

Pratt spokesman Mark Sullivan today cited a dramatic drop-off in demand for jet engines over the past three years as the major reason for the downsizing. The company will deliver less than 600 engines in 2000, compared to 800 in 1998, he said.

About 1,500 cuts will come from the hourly work force, mostly line workers in the company's East Hartford and North Haven plants, Sullivan said. The remaining 200 cuts will come from salaried workers who support those line operations, he said.

``In Georgia and Maine, where we also have manufacturing facilities, the impact will be minimal,'' he said.

The company employs 31,000 people worldwide and about 13,000 in the state of Connecticut.

Sullivan said the company has no news plans to close any manufacturing facilities. The company had previously announced it would be moving its military jet engine business and 2,800 jobs from Florida to Connecticut as part of its restructuring.

Pratt & Whitney, a United Technologies Co. division, designs, manufactures and services jet engines, space propulsion systems and industrial gas turbines.
