Well as OP thank you for all your input.I plan to either conduct the hours dual in a G registration aircraft (in as many individual sectors as my colleague desires) and then get an ICAA examiner of which we have access to plenty to sign the revalidation in his licence.Or as my colleague is regularly having LPCs on one of Boeings finest using that as a substitute for my instructional skills.Hopefully problem solved and my colleague continues to enjoy the delights of light aviation.I am sure George Orwell would have found inspiration for another book in the world of European bureaucracy ! Thank you again.
