Probable cause

The improper major repair of the carburetor heat control by unidentified persons that resulted the failure of the air intake distribution system and the loss of engine power.

Analysis

After takeoff from a touch and go landing the pilot reported that the engine lost power. The airplane entered a emergency descent and collided with some electrical wires before crashing onto a street off the airport. An examination of the carburetor air intake housing after the accident disclosed that the valve plate had been improperly installed by unidentified persons and had broken from the valve plate control shaft. The loose plate in the air intake housing would have the capability of reducing cold air to the carburetor and thus reducing power from the engine.
