## Discrepancy

AFTER TAKEOFF WHEN THE GEAR HANDLE WAS PLACED UP ALL THREE GREEN LIGHTS EXTINGUISHED. A LOUD METALLIC GRINDING TYPE NOISE WAS NOTED AFTER SEVERAL SECONDS (10-15) THE NOISE STOPPED AND THE GREEN LIGHT FOR THE NOSE GEAR ILLUMINATED. AT THIS TIME THE GEAR HANDLE WAS UP THE NOSE GEAR INDICATED DOWN, THE LT & RT MAIN GEAR DOORS WERE OPEN. WHEN THE GEAR HANDLE WAS PLACED DOWN NO ACTIVITY WAS NOTED VISUALLY OR NOISE BY THE GEAR, APPROX. 45-75 SECONDS LATER THE LT & RT MAIN GEAR DOWN LOCK GREEN LIGHTS ILLUMINATED AND THE RED DOOR LIGHTS EXTINGUISHED.
