The pilot was making a landing approach at the conclusion of a scenic flight. There were horses on the strip and the pilot elected to land long. The aircraft bounced on touchdown and recovery action was not effective before further bounces occurred. The pilot in the right hand seat took control and applied full power, however the aircraft settled into trees adjacent to the strip, and overturned. The strip surface was undulating and the landing was attempted in gusting crosswind conditions. The pilot occupying the right front seat had boarded the aircraft as a passenger. He had taken control of the aircraft because the actions of the pilot in command, following the bounced landing, were ineffective and the aircraft was heading for a building beside the strip. He had no instructional experience.
