DURING CRUISE FLT, THE HELICOPTER WENT OUT OF CONTROL & BEGAN AN UNCOMMANDED DESCENT. THE CYCLIC & COLLECTIVE CONTROLS WERE NON-RESPONSIVE, BUT LEFT PEDAL WAS APPLIED BEFORE THE HELICOPTER CRASHED & IT CRASHED IN A TAIL LOW ATTITUDE. AN EXAM OF THE FLT CONTROLS REVEALED THAT ONE MAIN ROTOR BLADE PITCH CHANGE HORN HAD FAILED, AS WELL AS THE ATTACHING BOLTSFOR BOTH PITCH CHANGE HORNS. THERE WAS EVIDENCE THAT ONE OF THE BOLTS HAD FAILED, THEN THE OTHER FAILURES WERE FROM OVERLOAD.
