Oil and Gas Operations in the Gulf of Mexico Claim 139 Lives in Helicopter Crashes ov
I've just come across the link to this study on the GOM done by John Hopkins Uni in the US which
examined fatal and nonfatal crash records of the National Transportation Safety Board (NTSB) from 1983 to 2009. Analyses determined that the most common result of mechanical failure in both fatal and nonfatal crashes was loss of engine power, which occurred in almost one-third of fatal crashes. The majority of forced landings following mechanical failure occurred in water, with 20 percent resulting in the sinking of the helicopter despite the fact that most helicopters are being equipped with pilotactivated flotation devices.
Bad weather was the second most common precipitating factor for fatal and nonfatal crashes and was responsible for the largest number of deaths. In fact, bad weather was the only factor that significantly increased the risk of pilot death when a crash occurred. Pilot error was a major contributor to 83 crashes (47 percent), with poor decision-making the most prevalent error.
“
Our findings suggest that efforts to reduce crashes and deaths must address mechanical failure, non-activation of flotation devices, and pilot error.”
The researchers also examined crash trends over the study time period and found an increase in the most recent time period, 8.2 annually during 2000 to 2009 versus 5.6 during 1983 to 1999. Following 2007, however, the researchers measured a decrease in crashes.
“Only time will tell whether this is a temporary statistical blip or the beginning of a positive trend.”
