N42336

The 2,000-hour private pilot of the single-engine airplane experienced a total loss of engine power during the initial climb. The pilot reported that about 400 feet above the ground (AGL), the engine "abruptly quit," and he attempted a left turn to attempt to return to the field; however, he impacted trees and then the ground before reaching the runway. The pilot also reported that he had topped-off the fuel tanks with 34 gallons of 100LL fuel at the airport 4 days earlier. An examination of the wreckage revealed that the carburetor bowl was half filled with what appeared to be rusty water. The gascolator was removed and examined. It did not contain any fluid; however, the inside of the bowl contained a large amount of corrosion. The wing fuel bladders tanks were empty, and no folds or obstructions were noted. The left fuel tank was breached, and no fuel cap was present. The vented right fuel cap was in good condition, with a pliable rubber gasket. No other evidence of preimpact mechanical failure or malfunction was observed. The airport fuel provider reported to the FAA that fuel samples were tested on the day of the accident and found to be within specification with no contaminants.
