11/30/2010. Remarks by Johan Visschedijk: "Produced in 2009, this aircraft is an unarmed version of the proven MBB BK 117 C-2 (later marketed as Eurocopter EC-145) and hence it was registered under the BK 117 C-2 Type Certificate as N591AE on February 4, 2009. It gained its CofA on March 20, and was deregistered April 15, 2006, and subsequently handed over to the US Army with serial 07-02063."
