## Discrepancy

DURING THE INITIAL CLIMB TO ALTITUDE, BOTH, LT & RT BLEED AIR ANNUNCIATOR LIGHTS ILLUMINATED SIMULTANEOUSLY.  RAN THE CHECKLIST FOR DUAL BLEED AIR LIGHTS & AFTER SEVERAL ATTEMPTS OF NOT BEING ABLE TO GET THE LIGHTS TO GO OUT & STAY OUT, WE DECIDED TO DIVERT.  PERFORMED LEAK CHECK OF BLEED AIR SYS, NO DEFECTS NOTED.  CHECKED BLEED LOOPS, WARNING SENSORS, FOR RESISTANCE, FOUND FAULTY BLEED LOOP.  REPLACED BLEED AIR SENSOR LINE.  SATISFACTORY FUNCTIONAL CHECK.
