## Discrepancy

(CAN) DURING TAXI PILOTS FELT THE RT WING DROP SUDDENLY AND HEARD A TIRE SKIDDING SOUND. THEY IMMEDIATELY STOPPED THE AIRCRAFT.  MECHANICS FOUND THE LANDING GEAR A-FRAME HAD BROKEN FREE FROM THE MAIN LANDING GEAR TRUNNION. THE LANDING GEAR DID NOT COLLAPSE BUT ROTATED OB AND CONTACTED THE WING WHEEL WELL SKIN CUTOUT, AFTER THE A-FRAME BECAME DISCONNECTED. THE A-FRAME THAT FAILED HAD BEEN REPLACED WITH AN IMPROVED DESIGN AS REQUIRED BY AD 97-06-10. A FLEET WIDE INSPECTION OF A-FRAMES IN SERVICE ON COMPANY OPERATED AIRCRAFT IS BEING CONDUCTED BY THE AMO TO DETECT EVIDENCE OF CRACKS AT THE WELD BETWEEN THE UPPER ATTACH FITTING (SQUARE SHAPE) AND THE ROUND TUBULAR STRUCTURE.
