According to the flight instructor, he was providing a check-out flight to the private pilot for the Cessna 152. The private pilot reported draining several ounces of water from the right wing fuel sump and gascolator during the preflight inspection and notified the instructor. The instructor requested additional fuel, and while they waited for the fuel truck to arrive, they continued to drain water from both wing tanks; the instructor estimated that they drained six or seven tubes of water from both wings. The airplane was refueled, and they waited about 10 minutes before sumping the fuel tanks again; they then sampled a couple of ounces of fuel from the right tank, which contained some water. They did not detect any additional water when they resampled the left fuel sump and gascolator. Both pilots reported that the engine run-up and takeoff were normal. They flew to the practice area and performed a series of maneuvers before returning to the departure airport for landing. The private pilot stated that about 3 miles southeast of the airport, the engine lost all power. The instructor then took the flight controls, trimmed the airplane for best glide, and continued toward the airport. Several attempts were made to restart the engine, and an emergency was declared to tower personnel. The instructor then landed the airplane in front of two fences; however, after landing the airplane impacted the second fence before nosing over and coming to rest inverted.
A Federal Aviation Administration (FAA) inspector, upon arrival at the accident site, noted that both wing fuel tanks had been compromised but that the wing fuel lines contained water. When a sample was taken from the gascolator, the FAA inspector reported that it contained 25 percent water. After a fuel source was supplied, the engine started and the power was manipulated through several cycles with no mechanical malfunctions that would have precluded normal operation.
Probable Cause: The failure of both pilots to ensure that no water was present in the fuel, which resulted in a complete loss of engine power and a forced off-field landing.
