Regulation 1178/2011, Article 9
1. In respect of issuing Part-FCL licences in accordance with Annex I, training commenced prior to the application of this Regulation in accordance with the Joint Aviation Authorities requirements and procedures, under the regulatory oversight of a Member State recommended for mutual recognition within the Joint Aviation Authorities’ system in relation to the relevant JAR, shall be given full credit provided that the training and testing were completed by 8 April 2016 at the latest.
Consequently, on the face of it, no training completed prior to 8 April 2012 can now be credited for the issue of an EU licence. However, the UK CAA is very good at finding ways around the regulations when it wants to so I should wait for the promised IN.
