We were just discussing the BAC 1-11 incident that nearly caused a catastrophy some years ago when the wrong bolts were fitted to a windscreen. Correct me if I am wrong, but was a managers' stamp used in that incident? We feel that the issuing of stamps for managers who used to be shop floor guys should be eliminated now before any more disasters occur. We feel that QA should have an approval renewal scheme whereby each approval is granted on the understanding that the holder is a 'hands on' person.
