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

During the initial climb after takeoff, about 100 feet above ground level, the engine experienced a total loss of power. The airplane struck the rooftop of a residence, and came to rest in trees, about 200 feet from the departure end of the runway. Examination of the airplane and engine did not reveal any pre-impact mechanical malfunctions; however, water was observed in the engine driven fuel pump, flow divider and gascolator. The airplane was equipped with sump drains at the lowest point in each tank. A drain valve was also installed in the fuel selector valve assembly. Additionally, the airplane information manual, normal procedures, pre-flight inspection section contained procedures to check for, and remove "sediment contamination and condensed water accumulation." The airplane was last refueled and flown the day before the accident.
