Analysis

Before flying a short distance to thomasville to refuel, the plt added 3 to 4 gal of auto fuel to the acft. At thomasville, the acft was serviced with 20.1 gal of aviation fuel. While taxiing to takeoff, the eng stopped & was restarted twice. After departing thomasville, the plt flew to the vicinity of a friend's farm about 11.5 mi away. While maneuvering in that area at about 300 ft AGL, the eng sputtered, stopped & restarted several times. A witness reported that the acft was gradually losing alt & speed when it suddenly made a 'nose dive into the gound.' About 20 sec after impacting, a fire erupted. The plt was found about 30 ft from the wreckage suffering from injuries & burns. He was hospitalized, but died 23 days later. The passenger died on impact & the acft was demolished by fire. No preimpact part failure or malfunction was found during the investigation.
