The co-owner observed the left wing was lower than the right wing and fuel was draining out of the fuel vent. The pilot moved the fuel selector valve handle from the both position to the right main fuel tank position. The pilot opened the left main fuel cap and stated the left main fuel tank was full. The co-owner opened the right main fuel cap and estimated about six gallons of fuel was present. The pilot started the airplane, taxied to the engine run up area, completed the engine run, and departed. The pilot turned right crosswind at about 50 feet and the engine lost power, The pilot lowered the nose, attempted to move the fuel selector valve from the right tank position to the left main fuel tank position which was unsuccessful. The engine started, stopped, and the pilot made a forced landing straight ahead into the trees. Examination of the airplane revealed the left and right main fuel tank were not ruptured. No fuel was present in the left main fuel tank and 5 gallons of fuel were removed by recovery personnel from the right main fuel tank. No fuel leakage was present on the ground. The airplane was recovered to a storage facility. The left and right main fuel tanks hold 18 gallons of fuel of which 1.5 gallons of fuel are not useable in non-level flight. The left and right main fuel tanks were filled with water and there was no evidence of leakage. Shop air was applied to the fuel system and no anomalies were noted. Plumbing for an external fuel source was connected into the left and right fuel tank supply line with a flexible hose for two engine runs. The fuel selector valve was placed in the left main fuel selector position for the first engine run and then on the right main fuel selector for the second engine run. The engine was started, the throttle was advanced to 1000 rpm and stabilized for 2 minutes. The throttle was advanced to 1500 rpm and a magneto check was conducted. The throttle was advanced to 2200 rpm and stabilized for 5 minutes, the engine was returned to the idle position, and shut down on both engine runs. No anomalies were noted during either engine run. ## Factual narrative HISTORY OF FLIGHT On July 1, 2006, at 1131 eastern daylight time, a Cessna 172H, N8084L, registered to two co-owners, operating as a 14 CFR Part 91 personal flight, had a total loss of engine power on initial take off climb in the vicinity of Ringgold, Georgia. Visual meteorological conditions prevailed and no flight plan was filed. The airplane received substantial damage. The commercial pilot reported serious injuries. The flight originated from Wilson Airport, Ringgold, Georgia, on July 1, 2006, at 1129. The pilot stated he and the co-owner arrived at the airport to pick up the airplane, which had just had an annual inspection. The co-owner observed the left wing was lower than the right wing and fuel was draining out of the fuel vent. The pilot entered the airplane and moved the fuel selector valve handle from the both position to the right main fuel tank position. The pilot opened the left main fuel cap and observed that the left main fuel tank was full. The co-owner opened the right main fuel cap and estimated about six gallons of fuel was present. The pilot completed the preflight inspection and no other anomalies were noted. The pilot entered the airplane, started the airplane, taxied to the engine run up area, completed the engine run, and no anomalies were noted. The pilot taxied into position on runway 21, set the brakes, and increased the power to full operating rpm. The rpm stabilized at 2200 rpm. The pilot released the brakes and began the take off roll. The airplane became airborne 1,000 feet down the turf runway and the pilot initiated a right crosswind turn about 50 feet above the trees. The engine quit, the pilot lowered the nose, and attempted to move the fuel selector valve from the right tank position to the left main fuel tank position. The shoulder harness was locked and he could not reach the fuel selector valve. The engine started again and stopped. The pilot made a forced landing straight ahead into the trees. PERSONNEL INFORMATION Review of information on file with the FAA Airman's Certification Division, Oklahoma City, Oklahoma, revealed the pilot was issued a commercial pilot certificate on December 11, 1968, with ratings for airplane single engine land, and multiengine land. The pilot was issued an instrument airplane rating on February 20, 1996.

METEOROLOGICAL INFORMATION The Lovell Field, Chattanooga, Tennessee, located 10 miles north of Ringgold, Georgia, 1153 surface weather observation was wind calm, visibility 10 miles, few clouds at 3,000 feet, temperature 82-degrees Fahrenheit, dew point temperature 66-degrees Fahrenheit, and altimeter 30.24. WRECKAGE AND IMPACT INFORMATION The airplane wreckage was located in a heavily wooded area adjacent to a private residence located at 6757 Three Notch Road and one and a half miles southwest of Wilson Airport in the vicinity of Ringgold, Georgia. The airplane collided with trees while descending and came to rest inverted on a heading of 333-degrees magnetic. Examination of the airplane revealed the engine remained attached to the airframe. The left aft, both forward engine mounts, and the No. 2 intake riser were damaged. The propeller remained attached to the propeller crankshaft flange. The propeller spinner was damaged. One propeller blade was not damaged. The remaining propeller blade was bent aft 10-degrees in the vicinity of the propeller blade tip. The cabin area remained intact. The throttle was in the full forward position and the mixture was in the full rich position. The carburetor heat was not activated. The fuel selector valve was in the off position. The pilot seat had separated from the seat track and the pilot seatbelt and shoulder harness were in use. Continuity of the flight controls was confirmed from the control yokes rearward to all flight control surfaces. The left and right main landing gear remained attached to the airframe. The right wing remained attached to the airframe and the leading edge of the wing was damaged. The right aileron remained attached to its hinge points and the flap was extended 10-degrees.The right main fuel tank was not ruptured. The right fuel cap gasket was hard and leaked water when the tank was leak tested. The rubber portion of the fuel cap vent was misshapen and did not seal correctly. Recovery personnel removed five gallons of fuel from the right main fuel tank. Blue staining was present on the top of the right main fuel cap. There was no leakage of fuel present on the ground. The right main wing strut remained attached at the wing and at the fuselage attachment point. The empennage, vertical fin, left and right horizontal stabilizers, left and right elevators, rudder assembly, and tail cone were damaged. The left wing remained attached to the airframe and the leading edge of the wing was damaged. The left aileron remained attached to its hinge points and the flap was extended 10-degrees. The left main fuel tank was not ruptured and the left main fuel cap gasket was hard and leaked during a water leak test of the tank. No fuel was present in the left main fuel tank and there was no leakage of fuel present on the ground. The left main wing strut was attached at the wing and at the fuselage attachment point. The FAA and parties to the NTSB investigation conducted a follow up investigation of the airframe, engine assembly, and accessories on July 6, 2006, in Griffin, Georgia. Recovery personnel removed the left and right wings from the airframe. Two cups of fuel was removed from the right main fuel tank and four ounces of fuel was removed from the firewall fuel strainer during the follow up examination. No fuel was present in the left main fuel tank. The left and right wings hold 18 gallons of fuel each of which 1.5 gallons of fuel are not useable in non-level flight. Each wing fuel tank was filled with water and displayed no evidence of leakage; however, both fuel caps leaked when the tanks were tipped up from the level position. Shop air was introduced to the fuel system at the firewall. When the fuel selector was moved to the right position, air flowed freely from the right fuel supply line at the wing root. When the fuel selector was moved to the left position air flowed freely from the left fuel supply line. No leaks were noted to either the left or right supply lines from the wing roots to the firewall fitting. Examination of the engine revealed all accessories remained attached and were not damaged.
