Given that BillieBob was at the 7/8 december EASA meeting where he voted yes
Given that proudprivate is a liar (or seriously ill-informed) I kinda doubt the value of anything that he posts. Just for the record, I was not present, in person, at the EASA meeting on either the 7th or the 8th December and, consequently, did not cast a vote in either direction. Also for the record, it is my personal and entirely uninformed opinion that proudprivate is seriously deluded - but then, what do I know?
EASA have stated and extended the date from 2012 to 2014 for the sole purpose of signing and agreeing a Bilateral agreement.
Not true. EASA are not in a position to determine an implementation date, that is already enshrined in EU law as 8 April 2012. EASA may 'recommend' a derogation to 2014 (as they have) but it is up to the EU parliament to agree this. However, given that the MEPs will vote only as their puppet-masters direct, this supposed control is entirely ineffective.
there are clearly no transitional arrangements in the document
There don't need to be - the amended ANO must become effective on 8 April 2012 to accord with EU law.
there isn't a definition of an EASA aircraft in the document
There doesn't need to be - an EASA aircraft is anything that is not included in Annex II to the Basic Regulation
If the aircraft is non-EASA by virtue of it being operated by an overseas operator
You clearly do not understand the concept of an EASA aircraft - a PA28 is an EASA aircraft irrespective of where it is registered or who operates it, as is a B747 or a Lear 45.
this will come as something of a shock to any foreign aircrew who might be resident in EASA
Precisely! Under the currently proposed amendment to Article 61 of the ANO, a Delta pilot resident in the UK would need an EASA licence to fly a Delta 767 into Gatwick notwithstanding the fact that the aircraft operator is not 'established' in an EU member state. This restriction, of course, exceeds the EASA requirement and is entirely illegal but, based on past CAA performance, is also entirely predictable.
