Trust · how acceptance works
Is online training accepted by EASA and the UK CAA?
Yes, when your Maintenance Organisation Exposition says so. No authority approves human factors or regulatory courses one by one; the rule puts the decision in your MOE. This page shows the clauses, what our certificate states, and how to check one.
What the rules require
Point 145.A.30(e) of Annex II to Regulation (EU) No 1321/2014 requires a maintenance organisation to establish and control the competency of its personnel, in accordance with a procedure and to a standard agreed with the competent authority, and says that competency must include an understanding of safety management principles, including human factors and human performance. Point 145.A.35(d)adds that certifying staff and support staff must receive sufficient training in each 2-year period to keep that knowledge current.
Neither clause names a delivery method. The acceptable means of compliance, AMC4 145.A.30(e), says safety training may be conducted by the maintenance organisation itself, by independent trainers, or by any training organisation acceptable to the competent authority, and that the training procedures should be specified in the MOE. AMC5 145.A.30(e) points to AMC 20-22 for EWIS and to Appendix IV to AMC5 145.A.30(e) for fuel tank safety, and Appendix IV expressly allows distance learning for Phase 2 provided the course evaluates the trainee along the way, records the examination and gives access to an instructor.
Who decides: your Maintenance Organisation Exposition
Point 145.A.70 makes the Maintenance Organisation Exposition the document in which the organisation describes its procedures, including its training and competency-assessment procedures. The competent authority approves the MOE. From then on, "accepted" has a precise meaning: a course is accepted when it meets the standard in your MOE training chapter. That is why the same certificate can be sufficient in one organisation and insufficient in another, and why the person to ask is your compliance monitoring manager, not the provider.
We build every course page to make that check quick. Each page states the clause the course serves, lists the syllabus against its reference (GM1 145.A.30(e) forSafety Training including Human Factors, Annex II itself for Part-145 Regulatory Training), says whether the course is Initial or Continuation, and states what the certificate says.
What a MOST.AERO certificate states
- Course name, including Initial or Continuation.
- Learner's name as entered at enrolment.
- Completion date, the day the final lesson was completed.
- Issuer: MOST.AERO, a brand of AEROVISER OÜ, Estonia.
Two honest limits. Our courses contain no examination, so the document is a certificate of completion, not a pass certificate; where a rule requires an examination, such as fuel tank safety Phase 2, your organisation must add one. And no expiry is printed, because the 2-year cycle under AMC4 145.A.30(e) and 145.A.35(d) is a duty of the organisation, which should anchor it on the training date in its own records.

How a compliance monitoring manager verifies a certificate
- Check the four fields above against the candidate's training record and your MOE training chapter.
- Open the matching course page on this site and compare the syllabus with the reference your MOE cites.
- Email info@most.aero with the learner's name, course and completion date. We confirm them against the learning record, which holds the enrolment, the lesson completions and the certificate date.
- File the certificate with your competency assessment under 145.A.55(d), for the duration of employment plus three years.
Part-147 organisation or non-147 provider: what the rule says
| Training | Who may deliver it, per the rule | Reference |
|---|---|---|
| Part-66 basic knowledge examinations | A Part-147 approved organisation or the competent authority only | 66.A.25(b) |
| Safety training including human factors, initial and continuation | The maintenance organisation itself, independent trainers, or any training organisation acceptable to the competent authority | AMC4 145.A.30(e)(d) |
| Fuel tank safety Phase 2 | An in-depth internal or external course, classroom or distance, with a multiple-choice examination at 75 % | Appendix IV to AMC5 145.A.30(e) |
| EWIS training programme | Built by the organisation on the AMC 20-22 model; classroom, computer-based or hands-on | AMC 20-22 §8 |
| Certifying and support staff 2-year training | A Part-147 organisation, an aeronautical college or the Part-145 organisation itself, among others | AMC1 145.A.35(d) point 4 |
The pattern is consistent: Part-147 approval is required where the rule says so, for licence examinations, and the organisation's own MOE governs everything under 145.A.30(e). MOST.AERO is not a Part-147 organisation and does not need to be for the courses it offers.

Frequently asked questions
Is MOST.AERO a Part-147 approved organisation?
No. MOST.AERO does not hold a Part-147 approval and does not present itself as holding one. Part-147 approval governs Part-66 basic and type training and the licence examinations under 66.A.25. The safety, human factors and regulatory training on this site is delivered under 145.A.30(e), where the standard is the one your organisation agrees with its competent authority and writes into its MOE.
Will my competent authority accept a MOST.AERO certificate?
The authority approves your Maintenance Organisation Exposition, and the MOE states which training your organisation accepts and how competency is assessed. If your MOE training chapter allows external and distance-learning providers and the syllabus matches the reference the MOE cites, the certificate is evidence within an approved procedure. If it does not, amend the MOE first or ask us to help you map the syllabus.
What exactly is printed on the certificate?
The course name, including whether it is Initial or Continuation, the learner’s name, the completion date and the issuer, MOST.AERO, a brand of AEROVISER OÜ. Our courses have no examination, so the document is a certificate of completion. No expiry date is printed; the 2-year cycle is your organisation’s to track, and the course page states which clause the course serves.
How do I verify a certificate a candidate shows me?
Email info@most.aero with the learner’s name, the course name and the completion date shown. We confirm against the learning record, which holds the enrolment, the lesson completions and the date the certificate was generated. We do not release any other personal data.
Does the same answer apply in the UK?
Yes. SI 2023/588 wrote the EU competency wording into UK 145.A.30(e) with the CAA as competent authority, and UK Part-145 training procedures still live in the MOE. The UK AMC and GM are in the CAA regulatory library; check them for CAA-specific wording before you write the chapter.
