We got our approval number by return of e-mail. I see there are currently 177 listed, against the CAA's expectation of about 250, so some must have fallen by the wayside. The whole thing was extensively advertised, so any RTF in current operation who hasn't registered has only themselves to blame.
The problem might come for students who are unaware of the requirement. We were careful to tell our students what was going on to assure them that their training remained valid and they weren't wasting money.
I'd be interested to hear if anyone has been inspected yet. The CAA are supposed to give 3 months notice and work to a 3-year cycle. That's just over 1 per week, not overly burdensome. I can't imagine it taking more than 1 day for a small outfit like ours.
