Aircraft Accident/Incident Report

Powder River, Wyoming 82648
Tuesady, February 27, 2001 14:30 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot had just completed a mission repositioning seismic equipment and was landing the helicopter on a snow and ice covered field in a confined staging area. He locked the collective control lever in the full down position, reduced power to 70 percent and opened the door to see if he had landed on one of his long lines. He inadvertently bumped the cyclic resulting in the helicopter turning to the right approximately 70 degrees allowing the lower vertical fin on the tail boom to come in contact with a metal gear/equipment cage. The structural integrity of the fin was compromised and required replacement.

NTSB Probable Cause Narrative

The pilot's failure to maintain aircraft control during aircraft shut down procedures. Contributing factors were: the snow and ice covered field and the confined landing areas unsuitable obstacle clearance.
