Who may deliver a TRI course and conduct a TRI Assessment of Competence

Scope: UK CAA application of Part-FCL (Subparts J and K), with practical guidance from CAA Standards Document 43 (TRI/SFI course providers) and Standards Document 24(A) Appendix 10 (examiner (a)(5) privileges). Aeroplane / MPA focus.

Important: Always verify against the current UK Aircrew Regulation (Part-FCL), the examiner’s licensing certificate privileges, and the latest CAA standards documents. This page is a working summary for MaxFli course directors and candidates — not legal advice and not a substitute for ATO approval conditions.


1. Who may deliver a TRI course

Requirement Who / what
Organisation A UK CAA Approved Training Organisation (ATO) with approval to conduct the relevant instructor course (TRI / SFI as applicable). Any ATO may apply for that approval; delivery is only after approval.
Oversight The ATO Head of Training (OR.ATO.110) is responsible for course standard and for training newly appointed Course Tutors (observation and supervised tuition).
Course Tutors (instructors on the TRI course) Must be qualified under the Aircrew Regulation; nominated by the ATO and notified to the CAA before use on the course.
Tutor privilege (Part-FCL) Tutors must satisfy FCL.905.TRI(b) and AMC1 FCL.930.TRI. In current UK CAA wording, privileges to instruct for the issue of a TRI or SFI certificate require the holder to: (i) have at least 50 hours of instructional experience as a TRI or SFI; and (ii) have conducted the flight-instruction syllabus of the relevant part of the TRI training course (FCL.930.TRI(a)(3)) to the satisfaction of the Head of Training of an ATO.
Recency Tutors need regular practice; the HT ensures skills/knowledge are maintained and that out-of-recency tutors receive refresher training before delivering a course (Standards Document 43).
Device Where FSTD training is used, the device must be appropriately qualified; Standards Document 43 expects a full flight simulator for the relevant elements.

MaxFli note: This MaxFli TRI pack supports ATO/instructor development. Delivery of a formal Part-FCL TRI course for licence/certificate issue still requires an approved ATO course and appropriately privileged tutors — not this pack alone.


2. Who may run an initial TRI Assessment of Competence (issue)

The initial TRI AoC (FCL.935 / FCL.935.TRI) is an examiner event, not a course-tutor event.

Requirement Who / what
Examiner certificate A TRE whose privileges include FCL.1005.TRE(a)(5) — commonly called “(a)(5)” privileges.
Experience & training At least 3 years as a TRE, plus specific training for instructor AoCs in accordance with FCL.1015(b) (and CAA evidence requirements for adding (a)(5)).
Equivalence Examiners must hold an equivalent instructor level to those they assess (FCL.1000 principle of equivalence). Example from SD24(A): a TRI restricted to FFS should be assessed by a TRE with matching TRI privileges (previous experience may satisfy policy).
Aircraft vs FSTD Match the privileges sought: simulator-only TRI → AoC in FFS; unrestricted aircraft TRI → AoC in aircraft by an examiner with full aircraft privileges (SD24(A) A10.2.2).
Vested interest (critical for initial issue) An examiner shall not conduct an AoC for the issue of an instructor certificate to an applicant to whom they have provided flight instruction during the instructor course (FCL.1005 / SD43 4.2.3). Course tutors who taught the candidate on the TRI course therefore cannot be the initial AoC examiner for that candidate.
SFE An SFE with FCL.1005.SFE(a)(5) may conduct AoCs for SFI certificates only — not for TRI.

On successful completion (and with required evidence), the examiner endorses the licence / licensing certificate as applicable.


3. Who may run a TRI AoC for revalidation (or renewal)

Requirement Who / what
Same examiner privilege The same (a)(5) TRE privileges cover AoCs for issue, revalidation and renewal of a TRI (or SFI) certificate (FCL.1005.TRE(a)(5); SD24(A) A10.1; SD43 4.2.3).
When an AoC is required TRI revalidation/renewal follows FCL.940.TRI. An AoC in accordance with FCL.935 is required at least every other revalidation (i.e. at least every six years), alongside the other revalidation options in Part-FCL. Renewal pathways may require refresher training at an ATO plus AoC — check current FCL.940.TRI.
Training before AoC All training for issue / revalidation / renewal of TRI/SFI must be by an ATO under an approved TRI/SFI course where training is required. If refresher training was done for revalidation, present the completion certificate to the AoC examiner (SD24(A) A10.2.1).
Multi-type If TRI/SFI is held on more than one type in the same category, an AoC on one type normally revalidates the others in that category unless OSD says otherwise.
No training during AoC Training of the instructor is not appropriate during an assessment of competence (SD24(A) A10.2.1).
Timing If the revalidation AoC is within 12 months of expiry, the new expiry is typically three years from the original expiry (extendable to end of month) — confirm current SD24(A) / Part-FCL wording.

Practical takeaway: Initial and revalidation TRI AoCs are both run by a TRE with (a)(5) (meeting the 3-year + specific-training conditions). The main extra constraint on initial issue is the no-self-examining rule after providing flight instruction on that candidate’s instructor course.
