Analysis

After a 5 hour flight in the motorized glider during which the engine was utilized on several occasions the pilot returned to his destination. Upon arrival he executed a number of low passes over the runway for photographers. The pilot executed a fly by confident that enough fuel remained for the maneuver. During the pullup the remaining fuel was exhausted and the pilot executed a forced landing. No fuel gauge nor low fuel warning indicator was installed in the aircraft and the pilot had no way of accurately determining fuel remaining. The plts flying time was not reported.
