Approach and Landing
The pilot initiated the approach to runway 36 with the expectation that the wind conditions would remain as earlier reported. Earlier, the wind had been from 330 degrees at 15 to 20 knots. However, by the time the pilot returned to land, the wind had reportedly become calm.
On the first approach, the aircraft was high, prompting the pilot to execute a go-around. During the second approach, the flaps were set at 30 degrees and the airspeed was between 75 and 80 miles per hour.
Runway Excursion
The pilot reported that the aircraft touched down approximately halfway down the 1800-foot sod strip. The remaining runway length was insufficient to stop the aircraft. Subsequently, the aircraft continued off the departure end of the runway and entered a ditch.
Inspection
No mechanical problems were reported with the aircraft.
