The Lead Auditor should prepare the AS9100 Audit Schedule Template and submit it to Top Management for approval. Audit schedules typically contain from four to eight audits per year, depending on the size and complexity of the company and its processes. Not every part of the company’s QMS requires an annual Internal Audit; however, every part of the QMS should be audited at least once every three (3) years. AS1200-1 AUDIT SCHEDULE specifies the areas to be audited and the time frame for each audit.
Certain areas (processes) may be audited more frequently, based on such factors as past nonconformities, risks of poor quality and their consequences, and customer feedback. Special (unscheduled) audits may be initiated by the Lead Auditor, with the approval of Top Management. The Lead Auditor should select an Audit Team for each audit. The size of the Audit Team will vary according to the area/process being audited. Specific dates for the Aerospace Audit Schedule will be developed and mutually agreed upon by the Lead Auditor and the Auditee.
Audit Team members may audit any area except those included in their defined responsibilities (e.g., a stamping machine operator may not participate in an audit of the Stamping area); this helps ensure auditor impartiality. To be considered competent, Internal Auditors must be trained in auditing practices and the requirements of the AS9100 standard. Before conducting audits on their own, new auditors should perform two audits with an experienced auditor.
