What was found
UPON LANDING AT KGYY AT APPROX. 8:00 P.M. ON THE NIGHT OF OCTOBER 21, 2019 AIRCRAFT N163DK FELT A ABNORMAL VIBRATION FORM THE LEFT MLG. THE AIRCRAFT TAXIED TO THE JET CENTER AND DISCOVERED THAT THE LEFT MLG UPPER AND LOWER TORQUE LINKS WERE SEPARATED FROM EACH OTHER. UPON INVESTIGATION WE DISCOVERED THAT THE BOLT THAT HOLDS THE TORQUE LINKS TOGETHER HAD SHEARED. THIS ALLOWED THE INNER STRUT AND LEFT MLG WHEELS TO BECOME INDEPENDENT FROM THE OUTER STRUT. WHEN THAT HAPPENED THE MLG WHEELS BEGIN TO VIBRATE AND THE INNER WHEEL HALVES BEGIN TO CONTACT THE UPPER TORQUE LINK CAUSING SEVERE DAMAGE TO THE WHEELS AND OUTER BRAKE ASSEMBLY. ALSO THE WEIGHT ON WHEELS SWITCH WAS RIPPED OUT OF THE LOWER TORQUE LINK.
