## Discrepancy

IN CRUISE FLIGHT, BOTH SYSTEM A LIGHTS (GREEN AND RED) FOR NOSE GEAR ILLUMINATED.  GEAR CYCLE ATTEMPTED, ALL RED LIGHTS ILLUMINATED EXCEPT RED NOSE A DISAGREEMENT.  NO GREEN LIGHTS.  APPROXIMATELY FIVE MINUTES LATER, PROBLEM CLEARED.  PROBLEM OCCURRED A SECOND TIME AND THEN CLEARED.  PERFORMED GEAR SWINGS (NO DEFECTS).  SWITCHED DOWN A AND B PROX SENSORS FOR TEST FLIGHT.  TEST FLIGHT SUCCESSFUL.  COULD NOT DUPLICATE PROBLEM.
