Hello Glenn.
It would seem that, not for the first time, the FAA have used the military serial for the cn.
I suggest you raise a new profile for the military version and the we (you or me!) can add cross referencing comments to both profiles.
It maybe heresy to say so, but I hope the day will come when we no longer rely on auto uploads from the FAA database and the many errors against N numbers can be corrected!
Malcolm.
