Analysis

The crew rprtd that drg takeoff, a power surge occurred after the acft had climbed about 400 to 500 ft. the coplt saw what he later said was a right fuel flow fluctuation & told the plt (PIC) that the right eng was losing power. The PIC told the coplt to secure the eng. Anticipating no serious problem, the PIC intended to remain in the pattern & make a single eng landing. However, he was unable to maint speed without dscndg & was forced to land. Subsequently, the acft went thru a fence, crossed a railroad track & stopped on a road. Drg an opnl check of the engs, the right eng started & ran normally. However, the left eng was difficult to start & would not run above 1000 RPM until another fuel metering valve was installed. A teardown of the faulty metering valve revealed contamination from an unknown source. Also, the left fuel pump discharge pressure was found to be 62 PSI. An adjustment of the altitude aneroid control returned the pump discharge pressure to within the max limit of 32.5 PSI.
