Busy FSDO’s have delegated this authority to Designated Pilot Examiners or DPE’s.
Unfortunately it counts for them as an “activity” and they are limited to two activities a day.
So some DPE’s would rather do two checkrides a day and some will therefore charge you the equivalent of what they would charge for a checkride.
You’ll get very little mercy from me as you need to consider the effort and cost involved if I want to get an equivalent EASA PPL let alone an ATPL.
