So under the rules (if they haven't been modified), you get a minor. You then must do a corrective action. The auditor verifies the effectiveness of the corrective action on the next audit. If a repeat is found, then yes a major is issued against your corrective action system, as it is deemed not effective because your corrective action allowed the repeat. Which, IMHO, is complete BS -- sometimes things don't work. I haven't heard that de-certification starts, but you must deal with the "major" in a timely basis.
