## Discrepancy

ON CLIMBOUT WITH GEAR HANDLE UP, GEAR MOMENTARILY BEGAN TO EXTEND (AMBER UNSAFE LIGHT ILLUMINATED) AND THEN RETRACTED AGAIN. PROBLEM REPEATED NUMEROUS TIMES. GEAR EXTENDED NORMALLY FOR LANDING BUT, LEFT GEAR DOOR LIGHT IS ON. ADJUSTED RIGHT & LEFT HAND MAIN LANDING GEAR PROX SENSORS AND DOOR SENSORS. NO PARTS REPLACED. OPERATIONAL CHECKS GOOD. AIRCRAFT RETURNED TO SERVICE.
