Maneuvering Observations
Witnesses near the airport reported seeing the aircraft maneuvering erratically and anticipated the accident. The first approach to Runway 25 was described as erratic with minimal apparent control. During this approach, the aircraft executed an abrupt pull-up, experienced a stall, bounced, and then performed a go-around in a left pattern at approximately 300 feet above ground level. The second base leg involved a very shallow turn, described as flat or skidding, after which the aircraft disappeared behind trees.
