FLC OF MLG HAS SPLIT FLAP INDICATION ON APCH. A GAR WAS MADE AND DETERMINATION THAT THE INDICATOR WAS THE PROB; NOT THE FLAPS SINCE NO ROLL CTL DEVELOPED. ABLE TO CORRECT TO NORMAL FLAP MOVEMENT AND LAND.

Narrative

A GAR AT LAX FOR RWY 25R DUE TO A SPLIT FLAP INDICATION ON FINAL APCH. R FLAP INDICATION WAS 15 DEGS AND L FLAP NEEDLE INDICATED ABOUT 23-25 DEGS. THERE WAS NO ROLL CTL PROB OR DISPLACED AILERON CTL. I SUSPECTED ONLY AN INDICATOR MALFUNCTION; BUT IT DID CAUSE FLAP MOVEMENT TO STOP. A MOMENTARY MOVEMENT OF THE ALTERNATE FLAP SWITCH REALIGNED THE NEEDLES AND NORMAL FLAP MOVEMENT WAS RESTORED VIA NORMAL FLAP HANDLE SELECTION. A NORMAL 30 DEG FLAP LNDG WAS MADE. HOWEVER; THE BOOK PROC WOULD HAVE BEEN TO LAND WITH A SPLIT FLAP INDICATION AND THUS NOT IN A NORMAL LNDG FLAP CONFIGN. I FELT THAT AS I STATED THAT THIS WAS PROBABLY NOT A TRUE SPLIT FLAP AND THEREFORE JUST AN INDICATOR PROB THAT STOPPED FLAP MOVEMENT. THE ASYMMETRY SWITCH FOR THE FLAP PROTECTION IS IN THE FLAP GAUGE. BY USING THE ALTERNATE FLAP EXTENSION; I BYPASSED THE ASYMMETRY SWITCH MOMENTARILY ENOUGH TO GET THINGS MOVING AGAIN AND AS THIS IS NOT A PUBLISHED PROC; I THEREFORE USED CAPT'S EMER AUTH TO PRODUCE THE DESIRED RESULTS; AND ELIMINATED THE HIGHEST LNDG SPD OF VREF 40 DEG FLAPS PLUS 40 KTS.
