Audit Team
For the past two years generally, audits are performed not by one Auditor, but by a team of auditors.
An Air Transport Inspector leads the audit and inspects Safety Systems ,an FOI inspects flying ops, AWI inspects Airworthiness, plus when or where required a DGI who inspects Dangerous Goods and a CSI who inspects Cabin Services.The group attend entry and exit meetings together, but split up during the audit, each into their own technical field.So it is quite plausible that components of the final audit report are dated with the same time,because several Inspectors may have interviewed several 'operator representatives' at the same time and in different locations,so the final report doesnt necessarily mean that only one auditor was involved in the audit.The final report is written by the Lead Auditor after lengthy discussions with the entire team.
