Accident Summary:
AT 1300 HOURS, AFTER PRE-FLIGHTING THE AIRCRAFT, CPT HAFNER AND CPT HALLEY TOOK OFF FROM THE CHRISTMAS TREE AT CAMP HOLLOWAY FOR A CHECK RIDE AT THE HOVER TEST AREA AT CAMP HOLLOWAY ARMY AIRFIELD. AFTER CPT HALLEY PERFORMED FOUR OR FIVE SUCCESSFUL LANDINGS, CPT HAFNER DEMONSTRATED A BASIC TOUCHDOWN AUTOROTATION ON THE PAVED STRIP AT THE HOVER TEST AREA. THEN CPT HAFNER INSTRUCTED CPT HALLEY TO PERFORM AN AUTOROTATION TO THE STRIP. CPT HALLEY ENTERED AUTOROTATION, AND THE PILOTS CHECKED THE GUAGES TO VERIFY THAT THE ROTOR WAS IN THE LOW GREEN AND THE N1 WAS 72 PERCENT.\\ AT 300 FEET AGL, IT BECAME APPARENT TO BOTH PILOTS, THAT THE AIRCRAFT WOULD LAND SHORT OF THE LANE, CO CPT HAFNER TOOK CONTROL OF THE AIRCRAFT, INTENDING TO MAKE A POWER RECOVERY. CPT HAFNER ATTEMPTED TO ROLL ON THE THROTTLE, BUT WAS UNABLE TO DO SO, BECAUSE THE THROTTLE WAS BINDING. HE CONTINUED TO ATTEMPT TO ROLL ON THE THROTTLE UNTIL HE WAS BETWEEN 75-100 FEET AGL WHEN HE REALIZED THAT HE WOULD HAVE TO COMPLETE THE AUTOROTATION TO THE GROUND. CPT HAFNER TRIED TO STRETCH HIS GLIDE. WHEN HE REACHED THE END OF THE LANE, HE FELT HE WAS TOO LOW TO DECELERATE MUCH WITHOUT STRIKING THE TAILBOOM. THEREFORE, HE BEGAN CUSHIONING THE AIRCRAFT WITH PITCH, AS THE AIRCRAFT FELL RAPIDLY THROUGH 10 FEET AGL.\\ HARD, HITTING FIRST ON THE LEFT REAR SKID, WITH A FORWARD GROUND SPEED OF 30-40 KNOTS. THE AIRCRAFT BOUNCED ABOUT TWO FEET UP IN THE AIR. CPT HAFNER STILL HAD DIRECTIONAL CONTROL OF THE AIRCRAFT. THE AIRCRAFT HIT THE LANE AGAIN, BUMPIN SIDE TO SIDE. IT THEN TURNED 90 DEGREES TO THE RIGHT, COMING TO REST 255 FEET FROM THE INITIAL POINT OF IMPACT.\\ CPT HAFNER THEN NOTIFIED B TROOP OPERATIONS AND THE CONTROL TOWER OF THE ACCIDENT, BY MEANS OF HIS RADIO. BOTH PILOTS, TOGETHER, WERE ABLE TO ROLL OFF THE THROTTLE. THEY SHUT DOWN THE AIRCRAFT AND EXITED. THERE WERE NO INJURIES AND THERE WAS NO FIRE.\\
