Analysis

The acft collided with the terrain in an uncontrolled descent following a partial loss of power during a takeoff climb. The plt stated the RPM dropped from 5200 to 4600 at which time he attempted to lean the mixture. A severe vibration developed and not wanting to fly over a residential area, the plt initiated a left bank toward the arpt. The acft stalled and entered a spin impacting the ground before recovery attempts were effective. Cause of the power loss was not determined.
