Narrative:
On approach the first officer selected flaps 15 and then flaps 20 with the final check. We noticed that the flap gauge was reading flap 0. The first officer recycled the flaps to 20 with no change in flight characteristics and no hydraulic pump running with flap deploy. We checked the circuit breakers and found none tripped. We notified ATC and executed a missed approach and entered the hold as published. The first officer ran the checklist for flap fault. I then transfered the controls the the first officer. I called the flight attendant who confirmed that the flaps were not down. We had neither a flap fault light or a bite light. I contacted dispatch and advised them of the situation and the fuel on board of 1200 pounds. We had braking action of poor for all runways and with the crosswind restriction of 5K we decided to land on 35. I ran the numbers for 35 with the malfunction increment chart. The fuel on board was now 1000 pounds. I advised dispatch that with the fuel on board we would land on 35 and call when on the ground. The first officer transferred the plane to me and we landed on 35 without incident. We stopped with normal braking and continued the taxi to the ramp.
