If you were to go to the website and review the enforcement policy and the specific procedures to be followed by inspectors, they are instructed that if they are advised of an occurrence that relates to a company that has an SMS or is working on an SMS, then they are not to take any action in enforcement or investigation, and they are to refer to the inspector responsible for that company, who will forward that information directly to the company and request that they handle the investigation and look into the occurrence in accordance with their safety management system.
The only caveat to that is where there is direct evidence of intentional wrongdoing from the outset. However, if an investigation never occurs, it's highly unlikely that an initial report will provide that information to an inspector.
