The pilot reported that after a cross country flight, while on final approach he realized the airplane was not centered on the runway and he executed a go around. The second approach was normal; during the landing flare the airplane “floated longer than usual” and drifted towards the right side of the runway. As the airplane touched down, the right main wheel fell into a trench and continued to traverse up a berm. Upon reaching the top, the airplane slid sideways along the berm until it came to a rest, substantially damaging the left wing and fuselage. The pilot reported no mechanical failures or malfunctions prior to the accident. The nearest weather reporting station located 12 miles southeast of the accident airport reported at the time of the accident wind was from 330 degrees at 9 knots.
