Factual narrative

On June 2, 2003, at 2029 mountain daylight time, an Airbus Industrie A319-111, N910FR, owned by Frontier Airlines, Inc., and operated as flight 045, encountered turbulence during final approach into Denver International Airport (DEN), Denver, Colorado. The airline transport certificated captain and first officer, 2 flight attendants, and 97 passengers were not injured; however, 1 flight attendant was seriously injured.
