On February 20, 1997, about 1645 eastern standard time, a Cessna 150, N11438, was substantially damaged when it collided with trees during the takeoff roll at the Haysfield Airport, Clarksville, Maryland. The certificated private pilot and passenger were not injured. Visual meteorological conditions prevailed for the local flight. There was no flight plan for the personal flight conducted under 14 CFR Part 91. In a statement submitted by the pilot, he stated: "We did a normal run up at the point half way up the hill on runway 13. Everything looked okay, controls worked okay, carburetor heat and magnetos checked okay. We taxied to the top of the hill and attempted to take off. Within seconds after we started to roll on runway 13, the plane veered to the left. I applied full right rudder. The plane straightened out but it had gone too far left. With the right peddle on the floor, the plane had straightened out fairly close to a line of small pine trees on the left side of the runway. The plane continued parallel to the trees for about 100 feet even though I continued full right rudder. Finally, the plane turned left into the trees." The pilot further stated that he "should have pulled power immediately when [the] plane went out of control." Examination of the wreckage by a Federal Aviation Administration Inspector did not disclose evidence of mechanical malfunction with the airplane, nor did the pilot report any. In the NTSB Form 6120.1/2, the pilot reported that the winds were from 310 degrees at 12 knots, gusting to 16.
