Can it be any FIE or only certain FIEs who have been standardized by the CAA?
In order
to conduct AoCs i.a.w. FCL.915(e)(3)(ii) a FIE must have completed an AoC themselves, successful completion of which is endorsed in their logbook. At least a few Senior Examiners have been authorised to conduct assessment of FIEs for addition of these privileges. CAA retain the claim to first dibs on conducting the assessment.
