## Discrepancy

L2 DOOR APPEARS TO BE INOPERATIVE. ACFT GROUNDED. FOUND THE L2 DOOR VERTICAL TORQUE TUBE TO BE LOOSE AT LOWER HINGE. REMOVED L2 DOOR FROM A/C. REMOVED WORN TORQUE TUBE ASSEMBLY & INSTALLED NEW TORQUE TUBE ASSEMBLY. REINSTALLED L2 DOOR ON A/C, ACCOMPLISHED RIG ADJUSTMENT, & DOOR SYSTEM TEST, TESTED GOOD. L-2 DOOR IS NOW FULLY OPERATIONAL. ALSO SEE LOG PG. # 11792915 FOR TORQUE TUBE REMOVE AND REPLACE.
