So if we put these two elements together, the audit program was a regular series of inspections, which were important in the same way that you have auditors checking financial books to avoid the kind of Enron management we occasionally see, and ensuring that this doesn't happen.
Killing the national audit program killed that attempt to do this on a regular basis. As I understand it, the civil aviation directive number 39 would not allow the inspections to take place, even when issues arose.
