What happened
A pilot was conducting an aerial application flight while working on a field operation. During the final phase of a spray pass, the aircraft collided with a shelterbelt. This impact caused the aircraft to lose control immediately.
Following the collision, the aircraft climbed to an altitude of approximately 300 feet before rolling completely inverted. The aircraft then impacted the ground in a nose-low attitude with one wing down. The pilot was unable to recall the accident clearly due to the nature of the event.
The investigation
The investigation focused on the mechanical condition of the aircraft and the sequence of events leading to the loss of control. Examination revealed that the initial loss of control was directly associated with the strike against the shelterbelt at the end of the spray pass.
Findings
The primary factor in this accident was the collision with the shelterbelt during low-altitude agricultural operations. The pilot's inability to provide a clear account of the event suggests significant disorientation or trauma during the incident. The aircraft's inverted position prior to ground impact indicates a rapid and uncontrollable aerodynamic response to the obstruction.
Safety message
Pilots conducting aerial application flights must maintain strict awareness of terrain obstacles, particularly shelterbelts that may not be visible from low altitudes. Adequate clearance should be maintained during spray passes to avoid sudden loss of control or structural damage.
