Probable cause

The pilot-in-command's failure to maintain airspeed. Factors contributing to the accident were a cracked carburetor float, fuel starvation, and the failure to perform an annual inspection.

Analysis

The airplane departed a restricted landing area runway for a local flight. Shortly after departing, at 300 feet above the ground, the airplane's engine stopped running. The pilot performed a 180 degree turn toward the departure runway. During the turn the airplane stalled and subsequently collided with the ground. The airplane was destroyed by a post impact fire. The on-scene investigation revealed a carburetor float with multiple cracks in it. Liquid emersion of the float revealed liquid penetration into the float. The last annual inspection was performed 21 months prior to the accident.
