Narrative:

While climbing thru 1;200 ft at full power over wooded area; the engine suddenly lost power and quit. An uneventful dead-stick landing followed in an empty grass field at a public park. No damage to aircraft or any property; and no injury to myself (only occupant) or any others. Upon inspection of engine after landing; it was found to be seized up. Later inspection of the intake port revealed metal debris from internal disintegration. Pilot/owner was lax in getting engine overhauled at manufacturer's tbo of 300 hours. Engine had 350 hours on it since last [overhaul]. I will be much more diligent in maintenance from now on. Lucky no one was hurt.
