Review of U.S. Civil Aviation Accidents, 2007-2009

According to National Transportation Safety Board (NTSB) statistics, more than half of tour helicopter accidents between 2007 and 2009 involved system or component failures. This statistic indicates that the air tour industry has a done a better job of reducing the human element, commonly referred to as pilot error, when compared with offshore and helicopter emergency medical service operators. It is also a stark reminder that helicopters are complex machines with many components that can fail and lead to a crash.
