Accident Details
During an en route descent at night to the destination airport, the airplane's engine lost power. The pilot subsequently executed a forced landing, during which the airplane impacted powerlines and poles, then crashed, and a fire erupted. Witnesses reported that engine noise was not heard.
Pilot Report and Fuel System
The pilot reported that one fuel tank showed rubber particles in the fuel each time he drained fuel, but the other fuel cell, which was replaced in January 1995, did not bleed rubber through the sump. The postimpact fire destroyed the fuel tanks and lines.
Postaccident Examination
The main fuel screen of the fuel control unit was clear of debris, and fuel was found in the fuel control unit and the fuel pump. One propeller blade had marks consistent with the powerline cable diameter. Flight control continuity was confirmed by tracing the airplane control cables.
Maintenance Records
Maintenance records did not reveal any open discrepancy.
Engine Test Run
During a postaccident engine test run, the engine performed within the manufacturer's specifications.
