| Confidence Rating: |  Accident investigation report completed and information captured |
The engine lost power as the pilot turned onto the downwind leg for landing. As the pilot approached a field for landing, the aircraft collided with a power line and then the ground. Postcrash examination of the engine showed it was operating with an excessive rich fuel mixture. The carburetor float was found stuck in the full needle valve open position due to excessive solder on the float fulcrum contacting the bowl wall. The carburetor had been recently modified by installing a new style needle valve, which also required the addition of weight to the float fulcrum with solder.
Probable Cause: Improper modification of the carburetor float by maintenance personnel resulting in the float sticking in the full needle valve open position and failure of the engine due to excessive fuel flow.
