## Discrepancy

MAIN CABIN DOOR DIFFICULT TO CLOSE, HANDLE BINDS AND CATCHES ON CLOSING. DIFFICULT TO OPEN AS WELL. PINS MOVE FREELY WHEN DOOR IS OPEN. NOTICED THAT THE PRECATCH RESET SHAFT HANDLE WAS SPINNING AND LOOSE. THIS SEEMS TO AFFECT WITH THE DOOR HANDLE BINDING.   ACCESSED AND NOTICED THAT THE SHAFT NUT WAS LOOSE. TIGHTEN THE NUT AND THE PRECATCH HANDLE STOPPED SPINNING. CLOSED ACCESS. LUBED ALL THE LINKAGES AND MOVING PARTS RELATED TO THE PRECATCH HANDLE. CLOSED THE MAIN CABIN DOOR MULTIPLE TIMES WITH NO DEFECT NOTED. REF AMM 52-10-00.
