Analysis

The acft collided with the ground while negotiating a low level aerobatic maneuver. The acft had departed a private ranch airstrip and according to a witness the acft was 'rolled'. After a few circles of the strip. The witness was surprised because the plt had said before takeoff that the acft was not suited for aerobatics. A 2nd roll was attempted but after the rollout 90 degrees off the entry heading the acft collided with the ground in a flat level attitude and skidded out of sight. The plt was fatally injured. He was an air transport plt with over 12000 hours total flying time.
