Visual meteorological conditions prevailed at the time. The pilot performed a procedure turn to align with the instrument approach. The engine lost power while turning inbound onto the final approach course. The airplane was at 2,300 feet mean sea level (~1,600 feet above ground level) when the engine lost power. The pilot switched back to the left fuel tank but the engine did not respond. The pilot performed a forced landing onto Interstate Highway 55. During the landing rollout the right wing impacted a mile-marker signpost. A post-accident investigation showed that the left and right fuel tanks were approximately 1/8 and 1/2 full, respectively. No anomalies were encountered during a post accident engine test run. The engine started without hesitation and responded to throttle inputs. The engine ran without difficulty on each fuel tank for a period of 4 minutes, on each magneto individually, and with the electric fuel pump turned off. ## Factual narrative During initial descent the pilot selected the right fuel tank for the practice instrument approach procedure.
