I think there could be other factors, 14 accidents from 110 aircraft does sound high (ish) but look at the facts.
This is the first fully articulated rotor headed helicopter with a fan and partial glass cockpit - It has advanced engineering and probably has some interesting flight characteristics as well. I would like to know the type hours of the pilots involved before drawing any conclusion, it would also be interesting to know what the accident rate was with the R22 when it first came out.
