Converting my UK A & C licence to a CAA AML JAR66 B1 / C including 13 type ratings back in '99 added up to £ 1167. Switzerland is not issuing any JAR66 licences at the moment.
The Swiss Federal Office for Civil Aviation ( FOCA ) is not ready to issue them at the moment. It looks like holders of a Swiss ICAO type II and type I maintenance licence will have a straight conversion, including transfer of all the type ratings free of charge, once the FOCA starts issuing JAR66 licences.
