## Discrepancy

FAILURE OF THE UPPER PART OF THE RIGHT MAIN GEAR, THE CYLINDER.   THIS FAILURE APPEAR TO BE A MECHANICAL FAILURE OF BOTH THE UPPER ATTACHMENT EARS FOR THE TORQUE LINK ASSEMBLY,  BOTH SECTIONS WERE SHEARED OFF.  THE SEPARATED SECTIONS SHOWS WHAT APPEARS TO BE EVIDENCE OF FIRST A BRITTLE FRACTURE OR CRACK AND THEN A DUCTILE FRACTURE, THIS ALLOWED THE STUB AXLE AND OLEO PISTON ASSEMBLY TO SEPARATE FROM THE CYLINDER.
