At approximately 14:25 CST, a Pietenpol Aircamper homebuilt airplane was substantially damaged when it struck a power line while maneuvering. The pilot was seriously injured. Witnesses said the airplane was maneuvering at low altitude. A nearby resident reported hearing the sound of the airplane engine flying near his residence. He said the sound of the engine stopped about the same time that his home lost electrical power. The resident went outside and observed that the single powerline servicing his home was down on the ground and the remains of the wood and fabric airplane had come to rest about 200 feet beyond the point where the wire was severed.
