Accident Overview
A helicopter was destroyed when it collided with the ground during a course reversal maneuver following an agricultural spraying operation. Ground witnesses reported that the pilot had completed spraying a cotton field and informed the ground flagger that the winds had shifted to a downwind condition. The pilot then initiated a 90-degree/270-degree course reversal turn, which was described by witnesses as a slow-airspeed, tight right turn followed by a tight left turn. The helicopter crashed during the left turn and was destroyed by impact forces and a post-impact fire.
Examination Findings
A post-accident examination of the helicopter revealed no evidence of any pre-existing malfunctions or failures. The investigation did not identify any mechanical or structural issues that could have contributed to the loss of control.
Maneuver Details
The course reversal maneuver was specifically characterized as a slow airspeed turn sequence. The pilot had just completed spraying operations and was adjusting to changing wind conditions, having noted a shift to a downwind situation. The loss of control occurred during the left turn portion of the reversal.
