## Discrepancy

ON A PART 91 FLIGHT THE GEAR DID NOT GET A LT DOWN LIGHT AND THE GEAR SELECTOR DID NOT COME BACK TO CENTER.  AFTER A SAFE LANDING FOUND THE SWITCH NOT OPENING ALL THE WAY.  CLEANED SWITCH AND BELIEVE THAT THE INTERNAL SPRING IS BROKEN AND ONLY ALLOWING HALF TRAVEL OUT AND NOT DISENGAGING SWITCH.
