I had a chat with my local board member last night. It seems this directive is related to audits - last year's. Something is still not up to scratch, when you read between the lines.
For my part, I don't believe there is any need for hysterical panic about groundings. The reality is the directive will likely have been a wake-up call, or a shot across the bow, of sorts, to bring whatever issue it is to a head (sent from CASA to RAA).
People need to relax a little - until such time as you are told to not fly your plane, there is nothing to panic about.
Did you pay your rego but not receive a new rego card? Normally you'd fly on, safe in the knowledge that you've paid and a card will arrive at some point, yes? Would not the same apply here? No-one has been told there rego has lapsed, have they?
Maybe I am too low strung... I can't register my new toy to me, currently. Paid for it last week, picked up yesterday...
I'm simply going to use up its existing rego until February, though I doubt it'll take that long to sort out.
Unstressed... that's me.
