The engine lost power during the initial climb through 500 feet. The pilot turned the airplane toward the airport and elected to execute a forced landing. The FAA inspector reported that the annual inspection was overdue, and that improper maintenance procedures used in the installation of the air filter and overdue annual inspection rendered the aircraft un-airworthy. Inspection of the induction system revealed that part of the filtering foam of the air filter was pinched between the filter screen and filter box. Further examination of the carburetor revealed that a 6 inch long and 1/4 inch wide piece of the filtering element was found lodged over metal vanes located at the carburetor venturi. The carburetor representative reported that: "The piece of foam would have not only reduced the airflow to the engine, but also caused the air fuel mixture to become too rich, both of which would tend to reduce power output."
Probable Cause: A partial loss of engine power due to a rich mixture and reduced airflow to the engine. Contributing factors were the owner's failure to obtain an annual inspection, and improper maintenance procedures used in the installation of the air filter.
