Aircraft Accident/Incident Report

Broomfield, Colorado 80021
Monday, September 11, 1995 10:53 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot took off from runway 29R with a left crosswind from 220 degrees at 20 knots. The pilot said that as the airplane lifted off, it was 'pushed down and to the right.' He surmised that he had encountered 'a severe downward and right moving gust of air.' Subsequently, the airplane collided with a taxiway sign and was damaged. A spokesman for the National Weather Service said there were 'convective showers off the foothills, causing scattered showers and gusty winds.'

NTSB Probable Cause Narrative

The pilot's inadequate compensation for the wind conditions, and his failure to maintain proper alignment with the runway after lift-off. A factor relating to the accident was: the unfavorable wind condition (gusty crosswind).
