KINGSTON, Okla. (AP) _ Two small airplanes collided over south-central Oklahoma early today and one of them crashed in a remote area, killing the pilot, officials said. The second plane suffered heavy damage but landed safely.

One plane landed at Texoma Airpark near Kingston. The wreckage of the second was found shortly before noon north of Kenefic, some 20 miles to the northeast.

The two people aboard the twin-engine Cessna that landed at the airpark were uninjured, but the pilot of the second plane, the only person aboard, was killed, said Bill Anderson, a spokesman for the Federal Aviation Administration office in Fort Worth, Texas.

''The pilot of the Cessna said he felt and heard a collision,'' said Anderson. ''He saw two rotating beacons going down.''

Anderson described the second craft as a Mitsubishi MU2 turboprop corporate aircraft. He said the Mitsubishi and the Cessna took off together from Tulsa and were headed together for Dallas.

Lake Texoma Park Manager J.C. Germany, whose house sits north of the runway at the resort, said he and his wife ran to the other end of their house when they heard the plane approaching the airstrip.

''It was extremely low and was making a tremendous noise,'' Germany said. ''We ran to the front of the house as it was approaching the back of our house.''

Anderson said neither pilot filed a flight plan. They were not under FAA control, he said. He declined to identify the pilot or the passenger on the Cessna.

John Ciasca Jr., manager of an FAA district office in Oklahoma City, said the small aircraft that landed had considerable damage.

''So he definitely hit something,'' Ciasca said.

Lake Texoma is about 120 miles south of Oklahoma City and straddles the Oklahoma-Texas border.
