Narrative:

Aircraft rolled on the runway and the pilot flying applied full power. After rotation; engine began running rough and the airplane was climbing at 100 ft/min. The airplane climbed to 400 ft over the runway and stopped climbing. Engine continued to run rough and instructor on board decided to return for a landing on the active runway. The pilot flying turned right crosswind; and the instructor advised the tower that the airplane had trouble climbing. We made right traffic at 400 ft and made a short approach; landing on the active runway. The aircraft landed safely and taxied to a maintenance facility.
