Narrative:
Our tire shop received a total of 22 reworked B767 main outboard (mob) wheel halves from a vendor. All received wheel halves had the proper FAA-8130 paperwork attached indicating the airworthiness of each wheel. Our shop procedure to return such wheels to service is to re-inspect according to our work documents and the component maintenance manual (cmm) 32-43-04. After completing the inspections on all 22 wheels; a total of three were found to be acceptable; for a failure rate of 86.4%. The majority of failures were related to improper blending procedures hidden under new paint and worn hub mating surfaces.
