On April 19, 2002, about 1804 central daylight time, a Lett R/Campbell K. AIRCAM homebuilt airplane, N912S, registered to Pike Aviation Inc., and operated by an individual, struck power lines, and impacted in a lake while maneuvering near Troy, Alabama. Visual meteorological conditions prevailed at the time. No flight plan was filed for the 14 CFR Part 91 personal flight. The airplane was destroyed. The airline transport-rated pilot reported serious injuries. The flight had departed from the Troy Airport, about 1715. The pilot stated in a letter that, "I have no recollection of the accident nor any other incidents which occurred on 4/19/02." According to witnesses, the airplane had been flying around the area low level for about 45 minutes, when it struck power lines, about 70 feet above a lake, and then fell into the water. The crash site was located about 2 to 3 miles southeast of the Troy Airport. According to witnesses at the scene the airplane was found lying inverted at the east end of the lake, in about 6 to 8 feet of water. The airplane was only partly submerged with the nose on the bottom of the lake. A witness jumped into the lake and rescued the pilot from the submerged wreckage. There were no reports of any mechanical problems before the airplane struck the power lines. There were no reported obstructions due to weather, and the reported visibility about the time of the accident was 10 statute miles. Toxicological tests were conducted on specimens obtained from the pilot during admission to the hospital by the Federal Aviation Administration, Research Laboratory, Oklahoma City, Oklahoma. The tests were negative for Ethanol in Serum, and positive for Lidocaine in Serum.
