What happened
The aircraft was operating in the local area, providing flights to relatives. Witnesses on the ground observed the airplane performing low-altitude maneuvers for more than one hour prior to the accident sequence. These maneuvers included repeated stalls and intentional engine power cuts.
During the final moments of the flight, witnesses saw the aircraft make a low-altitude pass over a residential structure. The airplane struck a roof-mounted antenna, which caused it to pull up slightly. Immediately after this impact, the aircraft collided with a powerline before descending to impact the ground.
