Looks like a document written by a paid Bell employee to tell the industry how much safer they'd be flying in a (Bell)206 than anything else. Does have some pertinent bits though. The Tree incident on page 33 is worth a good read!
As another member has pointed out, the CAA/EASA etc performance criteria are based only on engine isolation performace. Many other criteria introduced by the operators requirements (payload and redundancy of generators and hydraulics etc) mean in reality the choice of modern cheaper single engine helicopters is very limited in many circumstances.
