On January 17, 2005 at 1157 central standard time, a Cessna 152, N24218, registered to and operated by a private owner, collided with trees during a forced landing following a loss of engine power, two miles south of Nashville International Airport, Nashville, Tennessee. The instructional flight operated under Title 14 CFR Part 91. Visual meteorological conditions prevailed at the time of the accident and no flight plan was filed. The airplane was substantially damaged. The flight instructor received no injuries and the student pilot received minor injuries. The flight originated from Smyrna Airport, Smyrna, Tennessee, on January 17, 2005 at 1150. The instructional flight was approximately three miles south of Nashville International Airport at 1600 feet mean sea level (msl), when it was cleared to land at runway 2R. The engine began to lose power and then surged back up. The engine seemed to recover, then the power dropped again. The student pilot applied carburetor heat and the flight instructor took control of the airplane. He checked the carburetor heat and mixture, then pumped the throttle several times. The flight instructor pushed the carburetor heat in the off position and the engine's condition got worse. The engine continued to quit and then surge back up to full power. The flight instructor informed air traffic control that he was losing power and could not hold altitude. The airplane was approximately 1200 msl and the flight instructor knew they would not make it to the runway. The flight instructor selected a bare pasture on a short hilltop for the emergency landing. The instructor brought the airplane in over trees at the south end of the pasture with no power and full flaps. The airplane touched down on the pasture, but the instructor could not stop it before the crest of the hill. The airplane went over the crest and struck a tree with the right wing, spun around 180-degress, collided into more trees and then came to a rest. Examination of the airplane revealed the engine mounts broken, nose gear collapsed, both wings damaged and the empennage bent approximately 45-degrees to the left. Further examination of the engine revealed 18 gallons of fuel in the fuel tanks and very little fuel in the fuel lines or the carburetor. There was also no water found in the fuel lines or carburetor bowl. There were no anomalies found during the examination of the engine. At the time of the accident, the temperature was minus 4-degrees Celsius and the dewpoint was minus 16-degrees Celsius.
