The number of accidents and fatalities for business jet and turboprop operations worldwide increased substantially in the first nine months, compared with the same period last year. According to statistics gathered by AIN, U.S.-registered business jets suffered 22 accidents in the first three quarters versus 11 mishaps in the same period a year ago. There was one fatal accident for U.S. business jets in each of the two periods–four died in the April 2, 2011 accident involving a Gulfstream G650 on a test flight and two people were killed in the Jan. 5, 2010 crash of a charter Learjet 35A on a Part 91 positioning flight. Of the 31 U.S.-registered turboprop accidents worldwide in the first nine months of this year, 16 people died in seven accidents. In the same period last year, U.S.-registered turboprops were involved in 27 accidents, four of which killed 12. In September, 56 people were killed in two non-U.S.-registered charter jet accidents–a Boeing 737 in Resolute Bay, Canada, killing 12; and a Yak-42 in Russia that killed 44, including members of a noted Russian hockey team. Also in September, three non-U.S. registered turboprop fatal crashes–two in Indonesia and one in Canada–resulted in seven deaths.
