Analysis

The pilot departed from runway 15 and remained in a closed left traffic pattern. Witnesses observed the airplane on an extended downwind above a residental area between 50 and 150 feet AGL. The airplane was observed to make a left turn with an estimated angle of bank between 45 and 75 degrees. The nose pitched down 45 degrees and the airplane descended rapidly. The left wing tip collided with a roof top prior to the airplane crashing on the roof. Investigation revealed the flaperons and air brake were extended.
