## Discrepancy

WHILE COMPLETING AN ANNUAL INSPECTION, INSPECTED THE NOSE LANDING GEAR ASSEMBLY AND FOUND A SMALL CRACK ON THE FILLET WELD WHERE THE NOSE LANDING GEAR TUBE ENTERS THE REINFORCEMENT STRUCTURE, FORWARD LEFT SIDE. THE LARGE BOLT AND NUT WERE INSTALLED PER A PREVIOUS SERVICE BULLETIN. THE CRACK WAS NOT PRESENT DURING THE PAST ANNUAL INSPECTIONS COMPLETED BY THIS REPAIR STATION. REMOVED NOSE LANDING GEAR ASSEMBLY AND FOUND 2 MORE CRACKS THAT WERE COVERED BY THE NOSE GEAR PUCK STACK BRACKET. ONE CRACK IS 3/16" LONG AND THE SECOND CRACK IS 1.5" LONG ON THE TOP OF THE LANDING GEAR ASSEMBLY PLATE, STARTING AT THE PUCK STACK MOUNTING PLATE INSIDE END OF THE BOLT HOLES.
