Approach and Power Loss
According to the pilot, while approaching Collegedale Airport, he noticed the fuel level was getting low. The left fuel gauge indicated the tank was almost empty, while the right fuel gauge still indicated a quarter tank. While preparing for a visual approach to runway 21, the engine sputtered and then lost power.
Pilot Actions
He immediately turned toward runway 21 and attained best glide airspeed. At this time, he observed that he would not be able to reach the runway. He made a forced landing in a field adjacent to the airport and collided with a large fence post.
Post-Accident Examination
Examination of the airplane revealed that the right wing fuel cap was missing. The right side of the airplane fuselage beyond the rear window and along the side of the tail cone had blue streaks in a similar color to 100 octane low lead aviation fuel. Examination of the filler ports and fuel caps disclosed no failures to these components. The fuel cap was found on the runway at the Collegedale Airport.
