Aircraft involved

Probable cause & findings

The pilot's failure to execute a go-around when a normal approach to the intended landing point could not be maintained. An additional cause was the excessive descent rate that developed during the approach. Contributing factors were the tailwind condition and the tree line.

Factual narrative

The helicopter was substantially damaged during a hard landing. The pilot reported that he experienced a stuck microphone after takeoff and elected to return to the helipad for landing. He noted that reversing course for landing resulted in a right quartering tailwind on approach. The pilot reported that about 100 feet above ground level (agl), he noticed that the helicopter was not slowing down. His attempt to reduce the ground speed by "slipping" the aircraft was not successful. As the helicopter approached a line of trees, he turned toward an open area; however, the helicopter began to settle in the turn. He applied power in an attempt to reduce the descent rate and pitched up in order to position the helicopter for a hard landing. Although the descent rate began to decrease about 30 feet agl, the helicopter skids impacted the crest of a hill. The pilot added power and brought the helicopter to a hover, before landing near the heliport. The post accident examination revealed that the skids, lower fuselage and left stabilizer were damaged in the hard landing.
