The aircraft was to carry out insecticide spraying operations at a rice farm. The pilot made an approach to the airstrip from the south, with a tail wind of about 3 kts. The pilot said that, shortly after touchdown, he observed cattle straying near the edge of the strip and elected to go-around. As the aircraft became airborne the right main landing gear struck an adjacent levee bank. The impact detached the gear leg which then struck the right horizontal stabilizer, detaching the elevator. The pilot said that, by remaining in ground effect, he was able to complete a right circuit and land the aircraft back on the strip. On touchdown, directional control was lost and the aircraft ground looped, colliding with large water pipes and associated equipment.
