ufon, I would first apply for verification and then meet with a FSDO Inspector in person to find out exactly what he is requiring in your specific case.
If you are indeed required to perform a CTP, then you can select the best CTP training provider for you -- some CPT providers can use a FFS representing an aircraft weighing less than 40,000 Lbs if they were granted a deviation from 14 CFR 61.156 (as per FSIMS 8900.1 CHG 705). Check also AC 61-138. Good Luck!
PS. metric units such as Kg or Tons are not normally used by the FAA. When you meet with the FAA Inspector, make sure you speak the correct FAA language, and don't tell him how it is done in EASAland, and about all the EASA nonsense. BWDIK
