The pilot reported that the engine was not developing the expected rpm during the takeoff and initial climb. He noticed the airplane was not climbing well and could have trouble clearing small trees near the end of the runway. The pilot maneuvered the airplane through a low spot in the trees after he realized he did not have sufficient runway remaining to land. The pilot attempted to gain altitude and airspeed but only gained minimal altitude. The pilot considered applying carburetor heat but realized it would guarantee a loss of engine power with another line of trees ahead of the airplane. The pilot cleared the line of trees, but then impacted the next line of trees. The airplane nosed down, impacted the terrain, and came to rest inverted in a residential yard. The pilot speculated the reduced engine power was due to carburetor ice.
Postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operations. Weather conditions reported at the time of the accident were conducive for carburetor icing at glide and cruise power. The pilot reported that during the takeoff and initial climb, the carburetor heat was off. Therefore, it is likely that carburetor ice accumulated during taxi and run-up before the takeoff, which resulted in a partial loss of engine power and reduced takeoff performance.

Probable Cause: A partial loss of engine power due to the formation of carburetor ice while on the ground, which resulted in reduced climb capability and impact with trees during the initial climb.
