Background
The aircraft involved in the incident had not been operated for two years prior to the flight. During the preflight inspection, the pilot repeatedly drained the fuel sumps. On each occasion, a quantity of water was observed in the collected fuel sample.
Incident
Approximately 30 minutes after takeoff, the engine failed. The pilot executed a forced landing on a dirt road. During the landing roll, the right wing struck bushes, causing the aircraft to veer into a roadside ditch. The aircraft then flipped inverted.
Post-Accident Examination
A post-accident examination of the fuel system revealed the presence of water and other foreign matter within the system.
