Taken from a study of the Griffin Helicopters accident database since 09 Jan 1997 the study comprises a review of 405 rotary wing accidents and incidents involving UK registered aircraft of which 386 involved helicopters and 40 were fatal.

It should be noted that the role of the aircraft is not always clear from the accident report, as such the total number accidents will always be lower than that shown in the rest of the study.
