EASA Part-145 Regulatory Training – Initial
Online EASA Part-145 regulatory course on Regulation (EU) 1321/2014 Annex II: approval, personnel, MOE, management system. Certificate on completion.
Not a Part-147 approval and never presented as one. The certificate states the course name, the learner and the completion date; this page states the clause the course serves. Your MOE and competent authority decide acceptance. How organisations accept it
Regulation (EU) No 1321/2014 Annex II (Part-145)145.A.30145.A.35145.A.55145.A.65145.A.70145.A.200145.A.202
EASA Part-145 regulatory training is a guided walk through Annex II to Regulation (EU) No 1321/2014 — the rules your approval certificate, your maintenance organisation exposition and every certificate of release to service rest on. This online course takes Section A point by point, from scope and terms of approval to the management system at 145.A.200. It is self-paced and in English, and you finish with a completion certificate you can download and file.
Who must take this course (and why)
Part-145 never uses the phrase “regulatory training”. What it does is name people who have to know the Regulation. Point 145.A.30(a)(3) requires the accountable manager to demonstrate a basic understanding of this Regulation. Point 145.A.30(cc) requires the persons nominated under 145.A.30(b), (c) and (ca) — maintenance management, compliance monitoring and safety management — to demonstrate a working knowledge of it. Point 145.A.30(e) then requires the organisation to establish and control the competency of everyone involved in maintenance, airworthiness reviews, safety management and compliance monitoring.
AMC1 145.A.30(e) sets out what competent means for each job function: managers, planners, supervisors, mechanics, specialised services staff, support staff, certifying staff and compliance monitoring staff each get their own criteria. Read together, those points describe the audience for this course — quality and compliance monitoring staff, nominated post-holders, maintenance managers, planners, technical records and stores staff, and certifying staff preparing for an authorisation review. Staff arriving from a Part-21, Part-CAMO or non-EASA background usually need it most, because their working knowledge is of a different Annex.
What the regulation actually requires
Annex II has two sections. Section A is what the organisation must do; Section B is what the competent authority does when it certifies and oversees you. Section A runs from scope at 145.A.10 and application at 145.A.15, through terms of approval and scope of work at 145.A.20, facilities at 145.A.25, personnel at 145.A.30, certifying and support staff at 145.A.35, airworthiness review staff at 145.A.37, equipment and tools at 145.A.40, components at 145.A.42, maintenance data at 145.A.45, production planning at 145.A.47, performance of maintenance at 145.A.48 and certification of maintenance at 145.A.50.
The back half is the part quality staff live in: record-keeping at 145.A.55, occurrence reporting at 145.A.60, maintenance procedures at 145.A.65, the maintenance organisation exposition at 145.A.70, privileges at 145.A.75, changes at 145.A.85, continued validity at 145.A.90, and findings and observations at 145.A.95. Since Regulation (EU) 2021/1963 the safety management block sits at the end: 145.A.200 management system, 145.A.202 internal safety reporting scheme, and 145.A.205 contracting and subcontracting.
What the course covers
The course follows that structure in nine lessons after a free preview:
- Introduction to aviation regulations and EASA Part-145
- Approval and scope of work — 145.A.15 and 145.A.20
- Facility and infrastructure requirements — 145.A.25
- Personnel requirements — 145.A.30, including the competency duty at 145.A.30(e)
- Maintenance data, tool and material requirements — 145.A.40, 145.A.42 and 145.A.45
- Planning, performance and certification of maintenance — 145.A.47, 145.A.48 and 145.A.50
- Record-keeping, reporting and maintenance procedures — 145.A.55, 145.A.60 and 145.A.65
- Management system including safety management and compliance monitoring — 145.A.200 and 145.A.202
- Privileges and continuity of approval — 145.A.75, 145.A.85, 145.A.90 and 145.A.95
Each lesson ties the clause to the document it produces in a real organisation: the terms of approval, the MOE chapter, the work order, the certificate of release to service, the personnel record, the safety report.
Initial vs continuation — which one do you need?
This is the initial course, and it is the only version of it. Part-145 sets no fixed repeat cycle for regulatory training as such. The interval that does exist is 145.A.35(d), which requires certifying staff and support staff to receive sufficient training in each 2-year period so that their knowledge of relevant technologies, organisation procedures and safety management, including human factor issues, stays up to date. The safety management side of that 2-year duty is what the Safety Training including Human Factors Continuation course is for.
For regulatory knowledge the trigger is usually change rather than the calendar. A new amending regulation, a change to your terms of approval under 145.A.20, a new MOE revision under 145.A.70, or a finding under 145.A.95 all point at re-training a group of people. Your training needs analysis and the training procedures in the MOE decide who and when — not this page.
Exam, certificate and how organisations accept it
On completion you download a certificate issued by MOST.AERO, the training brand of AEROVISER OÜ in Estonia, naming the course and the date you finished. Put it in the personnel record your organisation must retain under 145.A.55(d) — records of qualifications, training and experience, kept for as long as the person works there and for at least three years after they leave.
MOST.AERO is not a Part-147 approved organisation and does not claim to be. Part-147 approval is about Part-66 basic and type training and the basic knowledge examinations, which under 66.A.25(b) may only be conducted by a Part-147 organisation or the competent authority. Training under 145.A.30(e) works differently: the standard is the one agreed with your competent authority and written into your MOE. For safety training, AMC4 145.A.30(e) accepts delivery by the maintenance organisation itself, by independent trainers, or by any training organisation acceptable to the competent authority. Check your MOE training chapter before buying for a team.
Price, access and how to enrol
The course costs €89 for one seat, paid once, with no subscription. It is delivered online and self-paced, so you start when you enrol and work through the lessons in your own time. Content is in English. The first lesson is a free preview, so you can see the register and depth before paying.
Enrol through the button on this page, which opens the course on the MOST.AERO store. You check out there; MOST.AERO is a brand of AEROVISER OÜ, Estonia. For several seats, a bulk invoice or a purchase order, email info@most.aero with the number of people and the courses you need, and we will set it up rather than asking your team to buy individually. Questions about whether the course fits your MOE are welcome before you buy — send us the training chapter reference and we will answer against the clause.

Frequently asked questions
Who needs Part-145 regulatory training?
Part-145 does not name a course called regulatory training. It names people who must know the rule: 145.A.30(a)(3) requires the accountable manager to demonstrate a basic understanding of the Regulation, and 145.A.30(cc) requires the nominated persons for maintenance, compliance monitoring and safety management to demonstrate a working knowledge of it. In practice the audience is quality and compliance staff, post-holders, managers, planners, technical records and stores staff, and certifying staff.
Is Part-145 regulatory training a legal requirement?
Not as a standalone course. The obligation is 145.A.30(e): the organisation must establish and control the competency of personnel involved in maintenance, airworthiness reviews, safety management and compliance monitoring, to a standard agreed with the competent authority. A regulatory course is one of the normal ways an organisation shows it has done that, and the training standard is described in the MOE under 145.A.70.
Does this course replace safety training including human factors?
No. Safety training including human factors is a separate obligation described in AMC4 145.A.30(e), with its own syllabus in GM1 145.A.30(e). This course explains how the Regulation is built; the safety training course covers the human factors and safety management syllabus. Most organisations run both.
Is MOST.AERO a Part-147 approved organisation?
No, and Part-147 approval is not what makes this course usable. Part-147 approval covers Part-66 basic and type training and the basic knowledge examinations under 66.A.25(b). Training delivered under 145.A.30(e) is judged against the standard agreed with your competent authority and written into your MOE.
How often does Part-145 regulatory training have to be repeated?
Part-145 sets no fixed interval for regulatory training itself. It does set 145.A.35(d): certifying staff and support staff must receive sufficient training in each 2-year period to keep their knowledge of relevant technologies, organisation procedures and safety management, including human factor issues, up to date. Your training needs analysis and MOE decide when regulatory content is repeated, and a rule change is the usual trigger.
Does the course cover the UK CAA version of Part-145?
The course is written on the EU text of Annex II. The UK assimilated version was amended by the Aviation Safety (Amendment) Regulations 2023 (SI 2023/588), which put the same management system wording into UK 145.A.200 and the same competency wording into UK 145.A.30(e), with the CAA as competent authority. The numbering of the nominated persons differs, and UK organisations had to close safety management findings before 1 July 2026.
What certificate do I get?
On completion you download a certificate issued by MOST.AERO, the training brand of AEROVISER OÜ in Estonia, naming the course and the completion date. File it in the personnel record your organisation has to keep under 145.A.55(d).
Can I buy seats for a team?
Yes. Enrolment is per seat on the MOST.AERO store. If you need several seats, an invoice or a purchase order, email info@most.aero and say how many people and which courses you need.
