On July 12, 1995, at 1641 eastern daylight time, a Cessna 152, N46911, operated by Stensin Aviation, was substantially damaged during a landing at Beaver County Airport, Beaver Falls, Pennsylvania. The student pilot was not injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the local training flight which was conducted under 14 CFR Part 91, and departed at 1620. In the NTSB Accident Report, the pilot reported: ...Upon landing for the third and final landing...I executed the landing as normal, touching down on the center line and at that time felt the aircraft skidding off to the side of the runway. Using rudder control, I attempted to guide the aircraft back onto the center of the runway unsuccessfully. The aircraft felt as though it was hydroplaning and that I had no control over its movement, although I continued to use rudder control. The aircraft skidded to the left, continued to roll over the grass and ran into brush and trees to the left of the runway. In a telephone interview, the FAA reported that no evidence of a mechanical failure or malfunction was found with the airplane. Runway 10/28 was 4501 feet long, 100 feet wide, and had an asphalt surface. The surface winds were reported to be from 290 degrees at 5 knots. The runway surface was dry. The student pilot had 31 hours total time, and was completing his 2nd supervised solo when the accident occurred.
