## Discrepancy

GEAR SEEMS TO WORK PROPERLY, BUT GEAR TRANSIT LIGHT STAYS ON WITH LEVER UP AND/OR DOWN.  RETURNED TO MSP.  FOUND LANDING GEAR CONTROL UNIT LAMPS TEST BUTTON STICKY.  REPLACED LANDING GEAR CONTROL UNIT PN D494-10-001, SN OFF 204/07-87, SN ON 095/07-85 IAW AMM 21-31-05-02 AND COMPLETED GEAR SWINGS IAW AMM 32-30-00.  ALL CHECKS GOOD.
