【 摘 要 】

An analysis of the frequency of four different types of rotorcraft accidents was conducted to determine if the number of fatalities and injuries between accident conditions was different. Accidents involving rollover, no rollover, fire, and no fire were studied to determine if accidents with a rollover or fire might be creating evacuation delays that contribute to the fatality and injury rates. A search of the FAA Accident Incident Data System from January1986 to March 1997 produced 2704 accident records for this analysis. A Chi-Square test for independence was used to determine the difference between the rollover and no rollover and fire and no fire accident categories.
