Incident Overview

During a series of landing attempts on Runway 21, an aircraft twice flared about 10 feet above the runway before initiating a go-around. On the second go-around, the aircraft appeared low and slow, and during a left turn descended into trees located on airport property.

Pilot Account

The pilot reported that gusting crosswinds pushed the aircraft away from the runway during each landing attempt. On the second go-around, a downdraft forced the aircraft into the trees after he had drifted left over wooded terrain. Additionally, the pilot stated that the carburetor heat was left in the on position during the second go-around.
