(-23) According to the pilot, the flight originated at the lakewood airport (N12), lakewood, new jersey. The pilot then flew to blm to pick up a passenger for a local flight. While he waited for the passenger to arrive, the pilot decided he would practice touch-and-go landings in the traffic pattern. He performed a preflight check and taxied to runway 14, "without performing a run-up check." After he taxied onto the runway, the pilot set the trim wheel 1/2 inch nose down, announced his departure, and applied full power. The pilot reported that he "felt nose-down pressure from the beginning of the takeoff roll." As the airplane accelerated, the pilot "wound off the trim" and at 55 knots, the airplane rotated. The pilot stated that immediately after takeoff, about 20 feet above the ground, the airplane dove toward the runway. The airplane struck the runway centerline with the nose gear, and bounced to "about the same altitude." The pilot reduced the power to idle, and applied full back pressure; however, the airplane entered a shallower dive than the first time, and again struck the runway centerline with the nose gear. The airplane then experienced a "small bounce" off the runway, and landed on the main gear. The pilot reported that rudder and yoke movement was hampered by "binding", as he taxied to the ramp. The pilot stated that he experienced no flight control difficulties prior to the accident. He further stated that the accident could have been caused by many possibilities, including,"...a stall, excessive nose-down trim, or a relaxed yoke."
