The pilot reported that during landing approach, when the airplane was about 50 ft above the ground, he pulled back on the engine power and the airplane stalled. The pilot applied 100% power to perform a go-around, but the left main landing gear struck the ground and the airplane bounced before becoming airborne again. The pilot flew the airplane back to the departure airport where he performed an overflight to ensure the landing gear was extended and landed uneventfully. The pilot noted in his report that fuel was leaking out of the left wing after the event. The manufacturer of the airplane performed an alignment symmetry inspection which revealed abnormal distortion and twisting of the left wing. The manufacturer recommended replacement of the left wing and placement of the fuselage in a fuselage jig to check for potential hidden damage.
