Not everything military is necessarily ITAR'd. A lot of components for legacy aircraft are now far outclassed by COTS equipment, or are now COTS equipment themselves, so there's not a need for especially stringent export/import requirements anymore. So these components might be removed from ITAR (Defense/State Department) control, and shifted to being controlled by the EAR (Export Administration Regulation) and the US Department of Commerce, which is less restrictive.
