## Discrepancy

UPLATCH CHECK WAS UNSATISFACTORY.  THE LEFT GEAR UNSAFE AND GEAR DOOR OPEN LIGHTS WERE ILLUMINATED.  THE GEAR WAS RECYCLED AND RECHECKED, BUT WAS STILL UNSATISFACTORY.  OPERATION WAS CONTINUED AT BELOW .70 MACH WITH RIGHT ENGINE HYDRAULICS ON HIGH.  MAINTENANCE FOUND THE LT MLG DOOR LATCH MECHANISM AT FAULT, ALLOWING THE DOOR TO DROOP WITH HYDRAULIC POWER OFF.  THE LATCH MECHANISM WAS REMOVED AND REPLACED IAW MM 32-31-4, PAGES 201-210.
