## Discrepancy

ORD-PIT - FLT 1272 - AFTER LANDING GEAR EXTENSION ALL THREE RED GEAR INDICATION LIGHTS REMAINED LIT.  THE LANDING GEAR WAS CYCLED AND ALL THE LIGHTS INDICATED GREEN.  MAINTENANCE INSPECTED ALL THE GEAR INDICATION SENSORS, JACKED THE AIRCRAFT AND PERFORMED MULTIPLE GEAR SWINGS.  THE INDICATION PROBLEM COULD NOT BE DUPLICATED.  (M)
