You will find that the JAR's are very vague about FTL's as they are mainly controlled by the Airline Unions/Operators policies of the various states or Airline. If they tried to publish all varients that encompassed all carriers in the EU then no one would fly. Unfortunately this opens the gate for non EU operators who proclaim that they operate under the JAR's to fly their crews to the limits and in fact break the rules! Hopefully when the EU Regs are totally analysed then operators into the EU will have to conform to a more stringently policed policy regarding FTL's.
