Read the full NTSB narrative
THE HELICOPTER WAS TOWED ON A TRAILER TO THE AREA WHERE IT WAS TO BE USED FOR AERIAL APPLICATION WORK. THE MAIN ROTOR BLADES WERE THEN SECURED TO THE ROTOR HEAD, BUT THE SHIPPING BLOCK WAS NOT REMOVED. DURING HIS PREFLIGHT, THE PILOT FAILED TO NOTICE THAT THE SHIPPING BLOCK WAS STILL IN PLACE. UPON TAKING OFF FROM THE TRAILER, THE PILOT WAS UNABLE TO MAINTAIN AIRCRAFT CONTROL BECAUSE THE SHIPPING BLOCK WAS RESTRICTING THE OPERATION OF THE FLIGHT CONTROL SYSTEM. THE HELICOPTER ENTERED AN UNCONTROLLED DESCENT, AND IMPACTED THE TERRAIN.
