Probable cause

Pilot in command failed to maintain airspeed during a forced landing resulting in a stall and hard landing after a engine power failure due to carburetor ice and improper use of the carburetor heat control by the pilot.

Analysis

The Cessna 152 departed on a local training flight with a student pilot and flight instructor on board. Approaching the departure end of the runway at approximately 500 feet a.g.l., a power loss occurred. Carburetor heat was applied, power momentarily regained and then power was lost again. A left turn back to the airport was made, however the aircraft landed in an area of brush and received substantial damage. The pilot said the terrain ahead had brush piles and a grape vineyard with poles.
