The NTSB's narrative final · quoted from the NTSB record

The private pilot reported that he performed a thorough preflight inspection and observed no contaminants in the fuel. He reported that, during cruise flight on a local sightseeing flight, the engine lost all power. The pilot could not restart the engine, so he performed a forced landing in a nearby field. During the landing roll, the airplane nosed over and then came to rest inverted, which resulted in structural damage to the airframe. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. During examination of the fuel system, water was found in the firewall-mounted fuel strainer. The left wing tank was dry; however, there was evidence of postaccident fuel leakage from the tank. The right wing tank was sumped using a standard 6-inch tube-type fuel tester. The tester was filled twice, and it only contained water each time. The tester was filled a third time, and it contained about 3/4 water and 1/4 fuel. Although the pilot reported that he performed a thorough preflight inspection, his inspection was not adequate because he failed to detect the water contamination.
