What is the ratio of helicopter crashes to light plane crashes?

Every other day I see light plane accidents mentioned on the news. I understand that helicopters are much safer, compared to light planes. Is there any data to show this? Aka, crash numbers / ratio etc?|||There are many reports which provide the information you're looking for. I've supplied links to two. Helicopters have about 30% more accidents per flight hour than general aviation fixed wing aircraft: helicopters about 8 per 100,000 flight hours compared to 6 per 100,000 flight hours fixed wing. Google helicopter accident statistics or aircraft accident statistics. Light airplane accidents get reported more frequently because there are probably more than ten times as many light planes as helicopters. Helicopters are very expensive to buy and operate.





Edit: Rotorwing. I agree about the safety of the Jetranger but the statistics I quoted are for all light helicopters. Turbine powered aircraft are much safer than recips but recips account for most of the accidents. Besides the inherent reliability of a turbine I suspect because of the cost more of the recips are not operated commercially and so do not have professional pilots and may not getting the same level of maintenance.|||I highly doubt that the accident rate for helicopters is 30% higher per flight hour.





Keep in mind that the saftest single engine AIRCRAFT is not an airplane but happens to be a Bell 206 helicopter according to the NTSB.|||I doubt helicopters are safer. There are more light plane crashes because there are more light planes. There are also many other factors.
