Narrative:
I was cleared for a visual approach to the nome airport. I began to configure for landing, flap extension went normally at 1 and 5 degree. Just outside the marker I requested gear down landing checklist flaps 15. The gear extended normally, however, the flaps froze at 9 degree with leading edge devices in the extend position. I elected to go around. The after takeoff checklist was completed with the flaps froze at 9 degree and anc center was advised we needed a holding clearance. I called for the 'symmetrical trailing edge flap failure' checklist. This checklist was accomplished to the descent/approach portion. Then we advised our dispatch and maintenance control, talked over the problem, and decided to call out nome crash fire rescue as a precautionary measure. When all was in place, we completed the symmetrical trailing edge flap failure checklist, requested an approach clearance and landed at nome.

Title: ACR MLG UNABLE TO GET FULL WING FLAP EXTENSION ON APCH TO OME AT NIGHT.
Narrative: I WAS CLRED FOR A VISUAL APCH TO THE NOME ARPT. I BEGAN TO CONFIGURE FOR LNDG, FLAP EXTENSION WENT NORMALLY AT 1 AND 5 DEG. JUST OUTSIDE THE MARKER I REQUESTED GEAR DOWN LNDG CHECKLIST FLAPS 15. THE GEAR EXTENDED NORMALLY, HOWEVER, THE FLAPS FROZE AT 9 DEG WITH LEADING EDGE DEVICES IN THE EXTEND POSITION. I ELECTED TO GO AROUND. THE AFTER TKOF CHECKLIST WAS COMPLETED WITH THE FLAPS FROZE AT 9 DEG AND ANC CENTER WAS ADVISED WE NEEDED A HOLDING CLRNC. I CALLED FOR THE 'SYMMETRICAL TRAILING EDGE FLAP FAILURE' CHECKLIST. THIS CHECKLIST WAS ACCOMPLISHED TO THE DSCNT/APCH PORTION. THEN WE ADVISED OUR DISPATCH AND MAINT CONTROL, TALKED OVER THE PROBLEM, AND DECIDED TO CALL OUT NOME CRASH FIRE RESCUE AS A PRECAUTIONARY MEASURE. WHEN ALL WAS IN PLACE, WE COMPLETED THE SYMMETRICAL TRAILING EDGE FLAP FAILURE CHECKLIST, REQUESTED AN APCH CLRNC AND LANDED AT NOME.
