NTSB Factual Report

The pilot stated he made an approach and landing to the landing pad. Upon landing, the pilot began reducing power, and reported that the helicopter was stabile for about 3 seconds and then part of the landing pad gave out. The pilot stated that the elevated landing pad has a clay foundation with a shell top and that recent rain may have compromised the landing pad stability. The helicopter rocked backwards and the tail skid struck the ground. The helicopter began rotating to the left and the pilot overcorrected to the right resulting in the helicopter colliding with trees. The pilot sustained minor injuries and the helicopter sustained substantial damage to the fuselage and the tail boom. After multiple requests, the pilot did not turn in the National Transportation Safety Board Form 6120.1 Pilot/Operator Aircraft Accident/Incident Report as requested.

The pilot verified that there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's overcorrection to the landing pad shifting, which resulted in the helicopter impacting trees. A factor contributing to the accident was the collapse of the landing pad.
