## Discrepancy

(CAN) MAIN LANDING GEAR DRIVE SHAFT RT INBD FOUND GROOVED DUE TO MISALIGNMENT OF THE MAIN LANDING GEAR, GEARBOX AND MOTOR ASSEMBLY.  THE TORQUE SHAFT WAS NOT CENTERED IN THE PRESSURE SEAL, RESULTING IN WEAR/DAMAGE TO THE SEAL AND LEAVING THE SHAFT IN DIRECT CONTACT WITH THE SEALS METAL FINGERS.  THIS CONDITION COULD LEAD TO EARLY SHAFT FAILURE.
