ARA.FCL.215
'The competent authority may develop procedures to allow privileges to be excercised by the certificate or licence holder, for a maximum period of 8 weeks after successful completion of the applicable examination(s)' pending endorsement on the licence or certificate'.
So slightly different wording, I got it from
http://eur-lex.europa.eu/LexUriServ/...01:0056:en:PDF
In the past, the UK CAA did not have a 'developed procedure', unless this has changed under EASA?
