This paper applies a methodology to combine different accident rates into an overall risk index taking into considerations the probability and severity of accidents, in order to compare the Canadian levels I & II air carriers with their U.S. counterparts operating under 14 CFR 121 and 14 CFR 135 during the 1988-1996 period. The analysis concluded that although Canadian air carriers had, on average, higher accident rates per 100,000 flying hours and per 100,000 departures than the U.S. air carriers, a statistical test of hypothesis on the overall risk index shows that the U.S. air carriers had, on average, twice as much risk as the Canadian air carriers which is not in agreement with previous U.S. studies.
