Narrative:

On approach to runway 14 in fwa, flaps were selected for landing (30 degrees). A flap indicator on outboard flap gauge showed 40 degrees. A flap lockout occurred and we were unable to move flaps. We followed abnormal procedures from pilot operating manual and with help of tower we stayed visibility an made a low approach to chock flap position. Tower advised us we looked 'normal.' we declared an emergency and landed west/O any further problem. Excellent cockpit resource management (CRM). We all took part in the solution. First officer and second officer did an excellent job of reviewing abnormal and I flew the aircraft and landed. We had a cable fail to the indicating system and we suspect we had only 25 degrees of flaps for landing. Tower was very helpful and it was good to see the quick response from the emergency equipment. Because of low altitude, we were unable to communicate with our company. Perhaps more air-to-ground frequency should be available to air carrier's. We did not need this, but in certain situations it could be helpful.

Title: AN ASSYMETRIC FLAP SITUATION ON FINAL APCH CAUSES AN ACR PIC TO ELECT A TWR FLYBY FOR A FLAP CHECK AND A CHECKLIST REVIEW WITH CRM PROC.

Narrative: ON APCH TO RWY 14 IN FWA, FLAPS WERE SELECTED FOR LNDG (30 DEGS). A FLAP INDICATOR ON OUTBOARD FLAP GAUGE SHOWED 40 DEGS. A FLAP LOCKOUT OCCURRED AND WE WERE UNABLE TO MOVE FLAPS. WE FOLLOWED ABNORMAL PROCS FROM PLT OPERATING MANUAL AND WITH HELP OF TWR WE STAYED VIS AN MADE A LOW APCH TO CHOCK FLAP POS. TWR ADVISED US WE LOOKED 'NORMAL.' WE DECLARED AN EMER AND LANDED W/O ANY FURTHER PROB. EXCELLENT COCKPIT RESOURCE MGMNT (CRM). WE ALL TOOK PART IN THE SOLUTION. F/O AND S/O DID AN EXCELLENT JOB OF REVIEWING ABNORMAL AND I FLEW THE ACFT AND LANDED. WE HAD A CABLE FAIL TO THE INDICATING SYS AND WE SUSPECT WE HAD ONLY 25 DEGS OF FLAPS FOR LNDG. TWR WAS VERY HELPFUL AND IT WAS GOOD TO SEE THE QUICK RESPONSE FROM THE EMER EQUIP. BECAUSE OF LOW ALT, WE WERE UNABLE TO COMMUNICATE WITH OUR COMPANY. PERHAPS MORE AIR-TO-GND FREQ SHOULD BE AVAILABLE TO ACR'S. WE DID NOT NEED THIS, BUT IN CERTAIN SITUATIONS IT COULD BE HELPFUL.
