While leveling the airplane after a descent from 3,000 feet to 1,500 feet, the pilot increased the throttle to level the airplane; however, engine power did not return, and the airplane continued to descend. The airplane subsequently impacted trees and terrain during a forced landing attempt. Witnesses reported hearing the engine "popping" and "sputtering" as the airplane descended. Following the accident, the engine was removed from the airframe and test run. During the first test run the engine exhibited varying interruptions of power, and when the throttle was increased to full, it reached a maximum rpm of 1,450. Troubleshooting revealed that all six fuel injector lines were loosely attached to the fuel manifold valve. After all of the lines were tightened, the engine ran without any interruption of power, and reached a maximum rpm of 2,644. Examination of maintenance records revealed that significant maintenance had been performed on the engine 7 months, and 246 flight hours, prior to the accident flight. Additionally, four of the six fuel injector nozzles were replaced about 6 months before the accident flight.
