Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The private pilot established a descent from a cruise altitude of 8,500 feet for an approach and landing to refuel on the second leg of a cross-country flight. At an altitude of about 5,000 feet, the engine stopped producing power. The pilot attempted to restore power by adjusting the throttle, mixture, and magnetos. The engine lost power completely. The pilot then attempted a restart and was unsuccessful. A forced landing was made to an open field between two rows of houses. During the landing roll, the airplane's wings hit a stop sign and several trees. According to a Federal Aviation Administration inspector on scene, the engine had compression, turned over by hand, and showed no outward signs of failure. No reason could be determined for the loss of engine power.
