My CPL has expired its a JAR 5 yr jobby,and ive no intention of renewing it.
Why not? Compare the cost of renewing it every 5 years with trying to get it back should you ever want it again! Your lifetime PPL will cease to exist in 2012 when EASA take over, so you will have to renew it every 5 years anyway, the cost of renewal will then be little different from renewing the CPL. Why throw away something that is hard earned?
If you have the original RT licence that states it is for lifetime (that actually means the lifetime of the pilot licence to which it is attached, not your lifetime) then provided you have the pilot licence bearing the same number then it is legally valid and you don't need another one.
The validity of the RFTOL changed because it was simpler to synchronise it with the flight crew licence to which it is attached. As there is no cost involved to the holder it makes little odds.
The simplest thing is to tell them that they have changed the address on your PPL but not your RT Licence and ask for an amended FRTOL.
