On December 2, 2003, at 1950 central standard time, a Cessna 182-K, N3056Q, registered to Cowarts Construction Company, and operated by the private pilot, collided with a power line and subsequently the ground while on approach to Birmingham International Airport, Birmingham, Alabama. The flight was operated under the provisions of Title 14, CFR Part 91, and instrument flight rules. Visual meteorological conditions prevailed and an instrument flight plan was filed. The pilot and two passengers received minor injuries and the airplane sustained substantial damage. The flight originated from Salem Airport, Salem, Arkansas, on December 2, 2003, at 1700. The pilot stated that the flight was uneventful until the approach to land in Birmingham. The pilot pulled the manifold pressure to 12.5 inches to descend and added power to align with the glide slope, but the engine did not respond. He then added full power, but still nothing happened. The pilot informed the control tower that he had a loss of power and proceeded to set up for an emergency landing. He stated the airplane clipped a tree top and went through a power line before touching down on the ground. The pilot stated the airplane "landed hard," the nose gear collapsed, and the left wing collided with a light pole. Examination of the airplane found the left and right wings had spar and wing skin damage, the right stabilizer and the bottom of the airframe sustained crush damage. The nose gear was folded aft. Examination of the engine found the throttle cable separated from the throttle body arm. The throttle cable attaching bolt was still attached to the throttle body arm, the nut was missing and the bolt was not drilled for a cotter key. Additionally, the examination of the throttle cable assembly revealed that Airworthiness Directive 86-24-07 and Cessna Information Letter SE79-6 had not been complied with when the engine assembly was recently installed during the annual inspection.
