## Discrepancy

ON TAKEOFF, GEAR HANDLE IN OFF POSITION, THE NOSE GEAR IN-TRANSIT AND NOSE GEAR DOWN AND LOCK LIGHTS WERE ILLUMINATED.  CYCLED GEAR DOWN AND UP AND THEN TO OFF POSITION.  BOTH LIGHTS REMAINED ILLUMINATED.  NOSE GEAR VIEWER PORT WAS DARK INDICATING GEAR UP AND NOSE DOORS CLOSED.  APPEARS TO BE AN INDICATION PROBLEM.  INDICATIONS WERE NORMAL ON LANDING.
