The board also reviewed the use of C-130s by the U.S. Navy and U.S. Coast Guard. The Navy had been flying the C-130 since 1961. In that time‚ their class A mishap rate from 1961 to 1998 was 0.87 mishaps per 100‚000 flying hours. It was also found that they had zero class A mishaps since 1977. The available flying hours for the Coast Guard only dated back to 1983 but from 1983 to 1997‚ their class A mishap rate was 0.30‚ experiencing only one mishap. Between the years of 1961 to 1982‚ the Coast Guard
