General Maintenance Action
Incorrect / Not Installed / Unavailable Part; Procedure
Aircraft X was in maintenance with contracted maintenance servicer at the same time as Aircraft Y. A technician with contracted maintenance servicer apparently was confused on which aircraft required the left hand outboard main wheel to be changed due to wear. Aircraft X actually required the wheel change but the technician removed the main wheel assembly from Aircraft Y. [While] changing the parts in maintenance management software; I noticed that the serial number of wheel assembly coming off was not what we were tracking in maintenance management software (SN X). There paper work stated (SN Y). I contacted the contractor and asked them to verify the removed serial number. The double check and it was actually SN Y; not knowing that they actually removed it from the wrong tail number; I released the aircraft from maintenance. The technician should have paid closer attention to which aircraft required the wheel change. I should have researched further the history of the removed wheel serial number.
A&P Mechanic reported upon review; main gear tire was replaced on wrong aircraft by technician.
