What happened
The flight was conducted for the purpose of performing an aerial survey of livestock. During the operation, the observer in the aircraft identified cattle located within a cove. In response to this observation, the pilot executed a turn and descended to an altitude of approximately 100 feet above ground level (AGL). After leveling the aircraft, the pilot assessed the surrounding topography and determined that immediate action was required to avoid rising terrain.
The pilot reported that he instinctively initiated a left bank. Shortly thereafter, he lost positive control of the ailerons and perceived that the nose of the aircraft was tucking under. The aircraft subsequently struck hilly terrain.
The investigation
No mechanical examination or post-accident inspection details are provided in the source text. The narrative focuses exclusively on the pilot's actions and the immediate sequence of events leading to the impact.
Findings
The primary factor contributing to the accident was the loss of positive control during a low-altitude maneuver. The pilot's inability to maintain control while attempting to avoid terrain at approximately 100 feet AGL resulted in the collision with the ground.
