The pilot reported that, before the flight, he set a 30-minute fuel management timer to remind him to switch fuel tanks. The pilot took off and conducted flight maneuvers; he then returned to the airport to practice touch-and-go landings. The alarm from his fuel management timer activated while on short final for the first landing; however, he forgot to switch fuel tanks. During the initial climb after the fourth touch-and-go landing, the engine sputtered and lost power. The pilot attempted to land on a nearby taxiway that paralleled the runway; however, the pilot overshot the taxiway. As the pilot turned the airplane back towards the taxiway, he held too much back pressure on the yoke in order to remain airborne and stalled the airplane, about 15 ft above ground level. The airplane impacted the ground and came to rest on the taxiway. The airplane sustained substantial damage to the fuselage and to both wings. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airframe and engine that would have precluded normal operation. The pilot additionally stated that the accident could have been prevented if he had immediately switched to the other fuel tank when his fuel management timer alarm activated.
