Analysis

The ultralight acft crashed after takeoff when the engine failed at about 100 ft AGL. The acft climbed to about 100 ft AGL at a distance of about 240 ft from the end of the rwy. At this point the engine quit and the pilot started a 180 degree turn toward an open field adjacent to the rwy. During the turn the acft collided with the ground. Investigation revealed a steel ball in the fuel filter check valve became jammed which restricted fuel flow to the engine.
