AN EMERGENCY WAS DECLARED WITH ATC, THE QRH WAS COMPLIED WITH, AND THE ALTERNATE GEAR EXTENSION PROCEDURES WERE UTILIZED, WHICH RESULTED IN ALL 3 GOOD DOWN AND LOCKED INDICATIONS. CORRECTIVE ACTION: MAINTENANCE FOUND THE LEFT MAIN LANDING GEAR DOOR LATCH LOOSE AND MISSING TWO NUTS FOR THE ATTACH BOLTS. THE NUTS WERE INSTALLED, AND ALL FOUR NUTS WERE PROPERLY TORQUED. THE LEFT AND RIGHT GEAR DOOR SKIDS WERE REPLACED DUE TO HAVING RUNWAY CONTACT FROM ALTERNATE GEAR EXTENSION. EXCESSIVE AIR WAS REMOVED FROM BOTH THE LEFT AND RIGHT HYDRAULIC SYSTEMS.
