## Discrepancy

MCI - FLT 797 - AFTER TAKEOFF, THE LANDING GEAR WOULD NOT RETRACT AND THE GEAR INDICATION LIGHTS WENT OUT.  WHILE TROUBLESHOOTING AND PREPARING TO RETURN TO FIELD AT MCI, CREW FOUND THE AIR/GROUND SENSOR CIRCUIT BREAKER POPPED.  CREW RESET THE BREAKER AND MADE A NORMAL LANDING AT MCI.  NO EMERGENCY WAS DECLARED.  MAINTENANCE PERFORMED OPERATIONAL CHECK OF LANDING GEAR SYSTEM.  OPS CHECK GOOD.  COULD NOT DUPLICATE AIR/GROUND SENSOR CIRCUIT BREAKER TO POP.  (M)
