What happened
The pilot was tasked by a deputy sheriff to transport a helicopter approximately 2.5 miles to Minot International Airport for impoundment purposes. During the takeoff phase, the aircraft began to climb but the pilot subsequently lost control. The helicopter entered an uncontrolled descent and crashed shortly after leaving the ground.
Initial impact occurred roughly 35 feet from the departure point. The collision caused significant damage to the airframe, including separation of the tail boom, damage to the main rotor blades, bent skids, and a broken front glass canopy.
The investigation
A post-accident examination of the helicopter was conducted along with an engine run-up test. Investigators found no evidence of pre-impact mechanical malfunction or failure that would have contributed to the accident. The aircraft systems appeared functional prior to the loss of control.
Findings
The pilot reported having 1,100 hours of total time in this specific make and model of helicopter. However, he had not flown in the last 90 days prior to the incident. Additionally, while the pilot had undergone a recent medical examination, the medical examiner did not issue a valid certificate at that time.
The lack of recent flight experience and potential certification issues may have played a role in the loss of control during the critical takeoff phase.
