FCL.1005.TRE TRE – Privileges and conditions Regulation (EU) 2019/1747 (a) (b) TRE(A) and TRE(PL). The privileges of a TRE for aeroplanes or powered-lift aircraft are to conduct: (1) (2) (3) (4) (5) skill tests for the initial issue of type ratings for aeroplanes or powered-lift aircraft, as applicable; proficiency checks for revalidation or renewal of type ratings, EIRs and IRs; skill tests for ATPL(A) issue; skill tests for MPL issue, provided that the examiner has complied with the requirements in FCL.925; assessments of competence for the issue, revalidation or renewal of a TRI or SFI certificates in the applicable aircraft category, provided that they have completed at least 3 years as a TRE and have undergone specific training for the assessment of competence in accordance with point FCL.1015 (b).
The equivalent para 5 for SFEs:
5) assessments of competence for the issue, revalidation or renewal of an SFI certificate in the relevant aircraft category, provided that they have completed at least 3 years as an SFE(A) and have undergone specific training for the assessment of competence in accordance with point FCL.1015(b).
Which says to me that SFE can only qualify SFI. That is a surprise to me, but there we are.
