Narrative:

After normal departure, the flaps failed in the takeoff position. As we climbed out and worked the checklist it became obvious we could not cure the problem. I called ZNY and asked to return to teb (after we had burned enough fuel to land). ZNY took the initiative and declared an emergency for us, and we returned to teb for an uneventful landing. After we taxied into FBO hangar, the FAA inspected all our paperwork, and seemed satisfied. The malfunction was caused by a bad flap limit switch.
