In the strongest terms, I suggest avoiding AAR. Their business model treats air frames, both fixed and rotary, as ATMs from which to withdraw money. Limited money gets invested. I trained in a 55-year old Sikorsky Sk-61N with nearly 40,000 hours on it, getting insufficient mx. My scheduled ten-day type-rating training was on day 26 when I resigned, with no end in sight. One of the guys I was there with -- a long-time friend with whom I flew in Iraq -- took more than three months to complete the aircraft qual due to lack of training aircraft. The corporate offices are very disorganized and wholly unequipped to execute the contracts they have, let alone any new ones. They required hundreds of dollars in immunizations up front, but did not reimburse all of the "mandatory" shots. Consider DynCorp instead. Every large company has its' challenges -- and DynCorp does as well -- but they are well-resourced and aiorcraft mx is top-quality.
