Aircraft Accident/Incident Report

Paxson, Alaska 99737
Monday, February 10, 2003 11:00 AST

NTSB Narrative Summary Released at Completion of Accident

The helicopter pilot was conducting an aerial surveying flight over snow-covered terrain. During the survey operation, the pilot maneuvered the helicopter about 200 feet above ground level, while one of the passengers would drop stakes about every 800 feet along a property line. The pilot's attention was diverted inside the helicopter to monitor the global positioning system when the helicopter collided with terrain. The pilot said weather was not a factor in the accident. The helicopter impacted level terrain in a level attitude and rolled onto its side. The fuselage and rotor system received substantial damage.

NTSB Probable Cause Narrative

The pilot's failure to maintain altitude/clearance from terrain. A factor contributing to the accident was the pilot's attention being diverted inside the cockpit to look at the global positioning system.
