The passenger reported that the pilot departed the airport, completed a touch-and go, and flew to a practice area. The passenger then flew two clearing turns at 2,500 feet msl, and the pilot subsequently retook control of the airplane and climbed to 3,000 feet msl. After the pilot leveled the airplane about 2,900 feet msl, the engine lost all power. The pilot completed emergency checklist items, but was unable to restart the engine. The pilot then attempted a forced landing to a field. The airplane impacted in residential area; left wing low, nose down, and slid about 100 feet. Aside from a sooty number two cylinder, examination of the wreckage did not reveal any discrepancies. After the initial examination, the engine was then disassembled, and no discrepancies were observed. The fuel control unit, injector lines, nozzles, manifold, magnetos, number two cylinder and piston, and connecting rod, were all tested at the engine manufacturer's facility. The fuel components and magnetos flowed and tested within specifications respectively. The cause of the black sooty deposit within the number two cylinder could not be determined; however, the deposit appeared to be over normal combustion deposit. The National Transportation Safety Board determines the probable cause(s) of this accident as follows: A loss of engine power for undetermined reasons.
