Each service has a unique structure and we understand that. You are able to design as many user roles for your service and assign what priviledges each user role has. This keeps your data protected and allows modifications to be made by the correct personnel. Are you planning on selling an aircraft? You can create a user role for the buyer and allow only auditing records of that aircraft. Since all records are scanned into the system, records auditing can be performed from across the country and ensure a smooth transition.
