Probable cause

The pilot's failure to maintain helicopter control while landing, which resulted in a hard landing and subsequent roll over.

NTSB narrative

According to the airline transport pilot, he was dispatched on the emergency medical flight to an accident scene about 35 nautical miles from his base operations. The pilot checked the weather, completed the risk assessment form, and departed for the scene in the helicopter. He further stated that he climbed to 2,500 ft mean sea level and noted the winds to be from the southwest at 35 knots. He stated he was comfortable flying in these conditions and had flown in similar wind conditions several times before. The pilot stated that he was cautious of electrical wires that were next to the intended landing helipad. He came over the wires at 100 ft to clear them and then started to descend the helicopter at a rate of about 200 ft per minute. As the helicopter approached the ground, he increased the collective but was unable to slow the descent. The helicopter landed hard, bounced, and rolled onto its right side. The pilot stated that there were no known mechanical malfunctions or failures with the helicopter before the accident. Thus, it is likely that the pilot failed to maintain helicopter control while landing.
