Analysis

The acft collided with trees after the plt attempted an aerobatic maneuver at low alt. Witnesses said they observed the acft make a low pass over a house just before the accident. Then the acft started an aerobatic maneuver from 200 ft AGL.a corporate plt witness said the acft nose went up to about a 45 degree climb and the acft snap rolled. Instead of stopping the roll right side up the roll continued to the inverted position and the nose pitched down. The acft appearedto be recovering when it collided with trees in an upright position. The recovery was attempted the same as coming out of a loop or split's' maneuver. The trees that were hit were about 20 ft tall and the acft was in about a 20 degree nosedown attitude at impact.
