EASA Part-145 Regulatory Training – Initial

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.

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 [email protected] 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.
