At 0930 eastern time, a Cessna 150M was damaged during an aborted takeoff from a grass field in Jetersville. The pilot was not injured. The pilot said he landed in the field about 0900 and had previously operated from the field without any problems. He described the field as approximately 1,800 feet long and covered with grass that was approximately 4 to 5 inches high. At about 0930, he initiated his takeoff but the airplane would not accelerate past 50 knots. He decided to abort the liftoff, but the tires slid in the grass, which was wet from the morning dew, and the airplane slid into trees.
