THE PILOT ENCOUNTERED GROUND RESONANCE AFTER LANDING. THE HELICOPTER HAD TOUCHED DOWN LIGHTLY ON ITS LANDING GEAR SYSTEM AND BEGAN TO OSCILLATE FROM SIDE TO SIDE. THE HELICOPTER CONTINUED TO OSCILLATE UNTIL ONE SIDE OF THE HELICOPTER LANDING GEAR STRUCTURE FAILED. THE HELICOPTER THEN ROLLED ON ITS SIDE. THE FOUR LANDING GEAR DAMPERS AND TWO MAIN ROTOR DAMPERS WERE FOUND OUT OF LIMITS. THE ACCIDENT FLIGHT WAS THE FIRST FLIGHT AFTER A 50-HOUR INSPECTION WAS PERFORMED. DURING THE INSPECTION, THE LANDING GEAR DAMPERS SHOULD HAVE BEEN CHECKED FOR PROPER EXTENSION. THE LANDING GEAR AND MAIN ROTOR DAMPERS SHOULD ALSO BE CHECKED BY THE PILOT DURING HIS PREFLIGHT PREPARATION OF THE HELICOPTER.
Probable Cause: the operation of the helicopter with improper adjustment of the landing gear and main rotor dampers due to the inadequate maintenance inspection of the helicopter by maintenance personnel and an inadequate preflight inspection by the pilot.
