Narrative:
During descent at FL270, after turning on engine and wing anti-ice, the #1 leading edge flap indicated in transit with an amber light on pilot's panel. We were asked by center to keep our speed up during descent. We advised center that we would be slowing to 230 KTS for operational needs and they approved. After following the abnormal procedure in flight manual, we were able to determine the indication was an indicating circuit problem and there were no roll tendencies noted. To aid our descent with engines above flight idle with anti-ice on, we used speed brakes with the flap indications noted above. Landing was normal 30 degree flap landing at normal speed for our weight. An FAA maintenance inspector was riding in a cockpit jump seat and after landing commended us for the way we handled the situation and said we did a good job. Air carrier maintenance later confirmed our opinions and made the necessary repairs to the indicating circuit.

Title: AN ACR B727 CAPT RPTS THAT HE HAD AN ACFT EQUIP PROB #1 LEADING EDGE FLAP IN TRANSIT LIGHT ON. AN FAA ACR MAINT INSPECTOR WAS IN THE JUMP SEAT. THIS WAS AN INDICATOR PROB ONLY.
Narrative: DURING DSCNT AT FL270, AFTER TURNING ON ENG AND WING ANTI-ICE, THE #1 LEADING EDGE FLAP INDICATED IN TRANSIT WITH AN AMBER LIGHT ON PLT'S PANEL. WE WERE ASKED BY CTR TO KEEP OUR SPD UP DURING DSCNT. WE ADVISED CTR THAT WE WOULD BE SLOWING TO 230 KTS FOR OPERATIONAL NEEDS AND THEY APPROVED. AFTER FOLLOWING THE ABNORMAL PROC IN FLT MANUAL, WE WERE ABLE TO DETERMINE THE INDICATION WAS AN INDICATING CIRCUIT PROB AND THERE WERE NO ROLL TENDENCIES NOTED. TO AID OUR DSCNT WITH ENGS ABOVE FLT IDLE WITH ANTI-ICE ON, WE USED SPD BRAKES WITH THE FLAP INDICATIONS NOTED ABOVE. LNDG WAS NORMAL 30 DEG FLAP LNDG AT NORMAL SPD FOR OUR WT. AN FAA MAINT INSPECTOR WAS RIDING IN A COCKPIT JUMP SEAT AND AFTER LNDG COMMENDED US FOR THE WAY WE HANDLED THE SIT AND SAID WE DID A GOOD JOB. ACR MAINT LATER CONFIRMED OUR OPINIONS AND MADE THE NECESSARY REPAIRS TO THE INDICATING CIRCUIT.
