What was found
MED HANDLE IS STIFF TO CLOSE TO THE POINT IT AT TIMES WOULD LOCK. WHEN IT DOES LOCK, HAVE TO RESET THE SYSTEM IN ORDER FOR THE DOOR CAS MESSAGE TO CLEAR. C/W REPOSITIONED THE AIRCRAFT TO THE HANGAR DUE TO WEATHER. WE PERFORMED THE MAIN CABIN DOOR HEALTH CHECK PER MCC REQUEST. WE ALSO PERFORMED THE CABIN DOOR LATCH/LOCK SYSTEM FUNCTIONAL TEST IAW AMM 52-10-04, WHICH SHOWED MORE THAN 20 POUNDS TO MOVE THE HANDLE TO THE LOCKED POSITION. WE REMOVED THE OLD LUBRICANT FROM THE PINS AND LUBRICATED THE CABIN DOOR PINS WITH NEW LUBRICANT IAW AMM 12-20-40. THE HANDLE NOW CLOSES WITH 10 POUNDS OF FORCE. WE CYCLE THE HANDLE SEVERAL TIMES, AND THE DOOR LATCH/LOCKS AND UNLATCHES/UNLOCKS WITH NO ABNORMALITIES. ADVISED NJA MCC OF THE FINDINGS AND THEY ARE OK WITH RELEASING THE AIRCRAFT. NO FURTHER ACTION REQUIRED
