## Discrepancy

AFTER TAKEOFF GEAR HANDLE SELECTED UP, MAIN GEAR DOORS OPENED BUT GEAR DID NOT RETRACT.  RETURNED TO AIRPORT AND MAINTENANCE CHANGED THE GEAR SOLENOID DIRECTIONAL VALVE AND ACTUATOR PROXIMITY  SWITCH.  MAINTENANCE OPERATED LANDING GEAR WITH NO ISSUES AND AIRCRAFT WAS RETURNED TO SERVICE.
