Analysis

The plt was engaged by a deputy sheriff to fly the helicopter about 2-1/2 mi to the Minot intl arpt for impoundment. During takeoff, it began climbing, then the plt lost control & the helicopter entered a descent & crashed. Initial impact occurred about 35 ft from the departure point. During impact, the tail boom separated, the main rotor blades were damaged, the skids were bent & the front of the glass canopy was broken. The plt indicated that he had 1100 hrs total time in this make & model of helicopter, but had not flown in the last 90 days. He had a recent medical exam, but the medical examiner did not issue a certificate. During an exam of the helicopter & a subsequent eng run, no malfunction or failure was found that would have contributed to the accident.
