In the U.S.? Not even close  

First BK117 in North America was s/n 7002....i helped unload it off the flatbed at MBB in PA back in 1982.  Several more s/n BK's arrived over next few months...but could not be sold because the BK was still not Type Certified by FAA until a yr later.   Eventually 7002 was sold to Evergreen...who leased it back to MHC to use as a demonstrator.   US Jet took delivery of 7003...first EMS BK in US.   S/n if 7002 is still operating in Canada...it is undoubtely the oldest BK flying in NA, and possibly worldwide.   Oldest flying BK in US....is s/n 7012, which is still operated by DOE in S.C.   US Jet and Omniflight got most of the early (A-1) BK's....RMH a few yrs later.  s/n 7036 i believe was a RMH ship originally delivered to Detroit Med Ctr.
