The US National Transportation Safety Board (NTSB) has concluded safety in the country's civil aviation sector improved across most segments in 2010.
NTSB states based on preliminary data, 26 accidents were recorded for Part 121 carriers while Part 135 operators were involved in six accidents. All those accidents were non-fatal.
On demand operators, which comprise charter, air taxi, air tour and air medical operations, recorded a decrease in accidents from 47 in 2009 to 31 in 2010 despite a rise in flight hours from 2.90 million to 2.96 million. But fatal accidents for the group increased from two to six year-over-year.
NTSB states a decline in general aviation accidents is continuing. However, "this sector still accounts for the greatest number of civil aviation accidents and fatal accidents".
The board's preliminary calculations show 1,435 general aviation accidents in 2010, 267 of which were fatal, resulting in 450 fatalities.
