Narrative:
During test flight we tried to actuate the alternate flaps and got a leading edge slat disagree. We complied with checklist and tried to extend the trailing edge which also gave us a trailing disagree. We were unable to extend the slats/flaps using normal or alternate procedures. Declared an emergency and burned off some fuel to reduce our final approach speeds. Made a 'practice' no flap/no slat approach/go-around for familiarization of pitch and roll characteristics; came back and landed. After landing noticed that only the outboard leading edge slats were extended. Unknown what caused the malfunction.
