The NTSB's narrative final · quoted from the NTSB record

THE PILOT STATED THAT THE AIRCRAFT EXPERIENCED HYDRAULIC SYSTEM FAILURE FOLLOWED BY A LOSS OF ENGINE POWER. AN EMERGENCY AUTOROTATION LANDING WAS ATTEMPTED IN A PASTURE AND DURING THE LANDING THE AIRCRAFT WAS SUBSTANTIALLY DAMAGED. POST CRASH EXAMINATION REVEALED THAT THE HYDRAULIC FLUID HAD LEAKED OUT OF THE SYSTEM. HOWEVER, NO PRE-EXISTING FAILURE OR MALFUNCTION IN THE POWERPLANT SYSTEM COULD BE FOUND WHICH WOULD HAVE RESULTED IN A LOSS OF POWER. DURING ENGINE TEST RUN THE ENGINE OPERATED TO MANUFACTURER'S SPECIFICATIONS.
