## Discrepancy

AFTER SELECTING GEAR HANDLE UP, GEAR DOWN LIGHTS ILLUMINATED FOR APPROXIMATELY 5 MINUTES PLUS GEAR HANDLE LIGHT.  THEN HEARD A CLUNK IN NOSE WHEEL AREA AND GEAR RETRACTED NORMALLY.  AFTER INSPECTION, REMOVED AND REPLACED LANDING GEAR SELECTOR VALVE PER W/C 32-30-41R.  FUNCTIONAL CHECKS GOOD.
