| Nature: | Private |
| Departure airport: | , CA (KSBP) |
| Investigating agency: | NTSB |
| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that he was about 6 miles northwest of the airport, returning to the airport for landing, the engine abruptly and completely ceased delivering power. The aircraft descended through a stratus cloud layer and broke out beneath a 900-foot ceiling. The pilot determined that the aircraft would not glide to the airport and made an emergency landing in an open field beside a highway. The right wing struck a sign during the landing. FAA inspectors reported that the engine fuel sump contained a clear fluid resembling water, and that the right-hand fuel tank sump drain had a threaded plug installed which precluded routine sampling of the tank for water.
Probable Cause: The inadequate preflight inspection of the aircraft by the pilot-in-command which resulted in a loss of engine power due to water contamination in the fuel system. A factor in the accident was an improper maintenance alteration which disabled a fuel sump drain.
