Aircraft Accident/Incident Report

New Ulm, Texas 78950
Sunday, March 26, 2000 10:40 CST

NTSB Narrative Summary Released at Completion of Accident

The helicopter was transporting a passenger to a remote site to change the batteries on a seismic recorder box. As the pilot terminated the landing approach to a hover at a skid height of 1 to 2 feet above the ground, an empty canvas heli-bag that was lying on the ground blew into the helicopter's main rotor system. The helicopter developed 'a severe' vibration, the main rotor system separated, and the helicopter impacted the ground in a 'moderately hard landing.' The operator stated that the accident could have been prevented by 'making sure that heli-bag is secure and that aircraft is a safe distance from bag and box.'

NTSB Probable Cause Narrative

The pilot's inadequate in-flight evaluation of the landing area, which resulted in the separation of the main rotor system as a result of foreign object damage.
