On June 15, 1998, about 1515 central daylight time, a Cessna 152 airplane, N6217Q, registered to and operated by Higher Power Aviation of Arlington, Texas, was substantially damaged during a forced landing following a loss of engine power near Boyd, Texas. The solo student pilot was not injured. Visual meteorological conditions prevailed, and a flight plan was not filed for the 14 Code of Federal Regulations (CFR) Part 91 solo instructional flight. The local flight originated from Fort Worth, Texas, approximately 30 minutes prior to the accident. The 17 year old student pilot reported that he was flying the airplane in the local training area at a cruise altitude of 1,800 feet msl when the engine lost power. He "noted that the oil pressure read zero." The student pilot further stated that he initiated a forced landing to an open field, and the aircraft touched down at approximately 55 knots. During the landing roll, the aircraft went through a fence, impacted a tree, and nosed over coming to rest in the inverted position. Examination of the aircraft by an FAA inspector revealed that the right wing spar was bent, and the vertical stabilizer was damaged. The nose landing gear was collapsed aft, and the right main landing gear wheel was separated. Further examination of the airplane revealed the presence of fresh engine oil on the bottom portion of the fuselage, initiating in the area aft of the engine, continuing all the way back to the tail. The reason for the loss of engine oil could not be determined.
