## Discrepancy

PILOT REPORTED NORMAL LANDING GEAR INOP FOR EXTENSION, USED BOTTLE.  CREW REPORTED WHEN THE GEAR HANDLE WAS SELECTED DOWN, THERE WAS NO RESPONSE, NO NOISES - NOTHING.  TROUBLESHOOTING REVEALED SOLENOID -B- OF LANDING GEAR SELECTOR/DUMP VALVE READ OPEN ON CONTINUITY CHECK.  REPLACED LANDING GEAR SELECTOR/DUMP VALVE.  OPERATIONALLY TESTED OKAY.  AIRCRAFT RETURNED TO SERVICE.
