No Marty, the rules did not change, The FAA has always had these rules, they simply did not enforce them, they always assumed that any IA was an active A&P. Which as it turns out isn't true. There was no Notice to proposed rule change, no FAR got changed, the method of enforcement did.
As it turns out many IA holders were not working in the industry at all but keeping their IAs by attending the seminars. That ain't going to work any more.
