SA Part on AH-64
Sans, remember that the stabilator was not a part of the original AH design, so when they decided on having one, the Army could quite properly ( the UH-60 design now being in the public domain, so to speak ) offer them the technology and hardware. I might have mis-remembered the p/n format, but that was a 60 stabilator actuator on that 64.
Thanks,
