Narrative:
During approach to runway 8 in VMC conditions, flaps 5 degrees was called for during base turn. The trailing edge flaps moved to an unknown position and stopped. We repositioned the flaps to the up position and back to flaps 5 degrees. The flaps did not move. Called for and executed the symmetric non-normal trailing edge flaps or no flap checklist. The trailing edge flaps did not move with the alternate flap procedure. We elected to go around and run the opc with flaps less than 2 degrees with leading edge devices full extend to runway 8. The opc data allowed a landing on runway 8. With a target speed of 172 KTS we declared an emergency and briefed the flight attendants of the situation. Made a PA to our passenger about the flaps and precautionary fire trucks. The landing was uneventful. We requested the fire trucks follow us to the gate in case of tire fire or smoking brakes. We advised the ramp to stay clear of the landing gear because of possible hot brakes. Maintenance and dispatch were notified.

Title: B737-300 CREW RPTED THE TRAILING EDGE FLAPS REFUSED TO MOVE USING THE NORMAL OR ALTERNATE PROC. THEY LANDED WITH LEADING EDGE FLAPS IN FULL EXTEND, AND 0 DEG TRAILING EDGE FLAPS.
Narrative: DURING APCH TO RWY 8 IN VMC CONDITIONS, FLAPS 5 DEGS WAS CALLED FOR DURING BASE TURN. THE TRAILING EDGE FLAPS MOVED TO AN UNKNOWN POS AND STOPPED. WE REPOSITIONED THE FLAPS TO THE UP POS AND BACK TO FLAPS 5 DEGS. THE FLAPS DID NOT MOVE. CALLED FOR AND EXECUTED THE SYMMETRIC NON-NORMAL TRAILING EDGE FLAPS OR NO FLAP CHKLIST. THE TRAILING EDGE FLAPS DID NOT MOVE WITH THE ALTERNATE FLAP PROC. WE ELECTED TO GO AROUND AND RUN THE OPC WITH FLAPS LESS THAN 2 DEGS WITH LEADING EDGE DEVICES FULL EXTEND TO RWY 8. THE OPC DATA ALLOWED A LNDG ON RWY 8. WITH A TARGET SPD OF 172 KTS WE DECLARED AN EMER AND BRIEFED THE FLT ATTENDANTS OF THE SIT. MADE A PA TO OUR PAX ABOUT THE FLAPS AND PRECAUTIONARY FIRE TRUCKS. THE LNDG WAS UNEVENTFUL. WE REQUESTED THE FIRE TRUCKS FOLLOW US TO THE GATE IN CASE OF TIRE FIRE OR SMOKING BRAKES. WE ADVISED THE RAMP TO STAY CLR OF THE LNDG GEAR BECAUSE OF POSSIBLE HOT BRAKES. MAINT AND DISPATCH WERE NOTIFIED.
