Summary:
A Hiller helicopter with Phoenix conversion operated by Dynamics Aviation of
Vernal, Utah, lost its turbocharger while checking access routes into an oil
well area near the park and crash-landed on Harpers Corner Road.  None of the
three occupants - the pilot, his brother, and the pilot's seven-year-old son -
was injured.  The pilot walked several miles to an oil rig to call the park.
The rangers who responded were able to drive their vehicles to within 11 miles
of the crash site, then shifted to snowmobiles for the remaining distance.
All three occupants of the helicopter were back at park headquarters by 7:30
pm. The FAA and OAS were advised. The estimated damage to the helicopter is
about $50,000.
