Narrative:

After takeoff at about 200 AGL above the departure end of the runway xx the engine had a partial loss of power. Unsure of the condition of the engine I elected to make an immediate right turn to land; to the east; in an open grass area adjacent to a nearby controlled airport. In the turn; and sure that there was no conflicting traffic; I elected to not switch over to their tower frequency to call them; and just concentrated on flying the plane. The landing was uneventful. I called the tower to let them know what happened. It is very likely that they would not have been able to see the event due to my altitude and the trees between my flight path and the tower.a diversion to this landing sight is a regularly practiced engine out safety training procedure for all of the pilots flying at this airport. This was not an engine out 180. The landing area can be reached in about a 90 degree heading change.as of this writing; maintenance has found no reason for the partial power loss.
