Location:Dorado, PR -   United States of America

The private pilot had flown the airplane earlier in the day and had not noted any anomalies during that flight or during the preflight inspection and engine run up for the accident flight. About 15 minutes after takeoff on the accident flight, the pilot smelled smoke and decided to return to the departure airport. The smoke began to enter the cockpit, and the pilot conducted a precautionary landing in an open field; however, during the landing roll, the airplane impacted a drainage ditch. Postaccident examination of the airplane revealed evidence of engine compartment electrical arcing and melting of the plastic covering of the battery grounding wire. The source of the short circuit could not be determined.
Probable Cause: A short circuit of unknown origin, which resulted in electrical arcing in the engine compartment and smoke in the cockpit, which necessitated a precautionary landing to a field.
