Analysis

The plt reported that after a local flt he began a reduced power (1800 RPM) descent from 4500 ft MSL back to the arpt. At 3300 ft MSL the eng quit. The plt was unable to restart the eng as the prop was not windmilling & the acft was not equipped with an eng starter. The wing scraped a parked vehicle about 100 ft from the approach end of the rwy before the acft collided with a fence. The spark plugs & exhaust pipes were reportedly covered with black soot. The carburetor was not equipped with carburetor heat.
