## Discrepancy

VARIOUS DAMAGES AT THE AFT LANDING GEAR LOCATION, THE FIRST DAMAGE (#1) IS AT THE AFT LANDING GEAR CROSS BEAM SHIM (P/N: 350A214344.20) IN THE FORM OF CHAFING. THE CHAFE DAMAGE IS POSSIBLE DUE TO WEAR IN THE SHIM (P/N: 350A410064.20) BETWEEN THE AFT LANDING GEAR LOWER ARM AND LOWER HALF BEARING OR WEAR IN THE LOWER HALF BEARING (P/N: 350A410060.20) WHICH CREATED A SLIGHT LATERAL MOVEMENT OF LANDING GEAR CROSS TUBE AND CAUSED CHAFE DAMAGE TO THE LANDING GEAR CROSS BEAM SHIM. THE SECOND DAMAGE (#2) IS AT THE AFT LANDING GEAR CROSS BEAM (P/N: 350A214311.20) IN THE FORM OF CHAFING. THE LARGEST CHAFE DAMAGE AT LOWER SIDE OF THE CROSS BEAM WAS MEASURED TO BE APPROXIMATELY 0.3 IN LENGTH AND 0.015 IN DEPTH.
