Fort Collins Downtown Airport
Aircraft Accident/Incident Report

Fort Collins, Colorado 80524
Tuesady, May 4, 1999 10:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said that the wind was from 290 degrees at 10 knots with gusts to 20 knots 'or less.' After completing the pre-takeoff checklist, the pilot turned the airplane 360 degrees to check for traffic before taxiing onto the active runway. When the airplane had made a 180 degree turn (tail directly into the wind), an 'unexpected strong gust of wind' lifted the tail and the airplane nosed down. Another wind gust caused the airplane to nose over onto its back.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for wind conditions. A factor was the gusty wind conditions.
