Analysis

The acft collided with trees during a landing at a company helipad. The weather was IMC with low ceilings and fog. The acft had been cleared for a VOR approach monitored by radar. The co-plt spotted the pad and called it out to the plt who started a steep descent. While completing the landing check the co-plt sensed a nose high attitude of the acft and looked out. It appeared the acft was moving backward and down. He yelled 'where are we going?!' The captain added power as the acft entered the trees. The nose and right gear collapsed but the acft remained upright. The rotor blades were ruined by tree contact.
