Human Factors training
Human Factors All staff

Why capable engineers still make errors, and how to spot the conditions that set one up before it reaches the aircraft. Covers human performance and limitations, error and violations, handover and pressure, and the Safety Management System with just-culture reporting.

For Part-145 certifying staff and support staff, and for personnel involved in the delivery of the basic maintenance service - one Human Factors and SMS syllabus.

Fuel Tank Safety (CDCCL) training
Fuel Tank Safety (CDCCL) Phase 1 + 2 and Phase 2

A fuel tank explosion needs a flammable mixture of fuel and air and enough energy to ignite it. The design guards against it in two ways, ignition source prevention and flammability reduction, and maintenance has to keep those design features intact. These courses teach the two prevention concepts, Airworthiness Limitation Items and CDCCL, and how ordinary maintenance either protects those features or quietly removes them. The Phase 1 + 2 Initial course adds the Phase 1 awareness content.

For Part-145 staff who plan, perform, supervise, inspect or certify maintenance on affected aircraft and their fuel system components, and CAMO staff involved in the management and review of their continuing airworthiness. The Phase 1 + 2 Initial course covers both phases; the Phase 2 Initial course is for staff who have already completed Phase 1. The Phase 1 signature the appendix requires (the trainer's in Part-145, the reader's in a CAMO) stays with your organisation's own process.

EWIS training
EWIS Target Groups 1-2

Aircraft wiring is a system that ages in place for the whole life of the aeroplane. This course teaches wire and connector types, how damage and contamination arise, good installation practice and the inspection types, so that you can recognise an unsafe condition and deal with it to the data.

For staff who carry out EWIS maintenance (Group 1) or maintenance inspections on EWIS (Group 2). Other target groups (planners, cabin and flight crew) are out of scope.

Information Security (Part-IS) training

Maintenance now runs on digital information: loadable software, airworthiness records, test equipment and data portals. This course explains what Part-IS asks of your organisation and what you personally do to keep that information, and the aircraft that depend on it, safe.

Information security awareness under Part-IS (Reg (EU) 2023/203, Part-IS.I.OR) for anyone working in a Part-145 organisation, a CAMO or a CAO.

What every course gives you

Built to satisfy the AMC training criteria — and to actually teach

A recognised, verifiable certificate

Pass the exam and download a branded certificate with your name, the AMC citations, issue and refresh-due dates and a unique ID that anyone can verify online — an acceptable training record for your AMO.

Mapped to the AMC, section by section

Every course carries a syllabus-coverage table linking each lesson to its AMC clause (145.A.30(e), Appendix IV for Fuel Tank Safety, AMC 20-22 for EWIS, IS.I.OR.240 for Information Security) — the traceability your quality system looks for.

Real lessons, not tick-boxes

Written by engineers for engineers: the why behind each rule, worked “in the hangar” scenarios, comparison tables and key-takeaway callouts — a refresher actually worth your time.

Knowledge checks + a 75% exam

Each section gates on a short knowledge check, then a multiple-choice final exam with a 75% pass mark and unlimited retakes.

A refresh date on every certificate

Each certificate shows a “Refresh due by” date 24 months after issue. Your full certificate history is kept in My Training, and a course that is due is flagged with a one-click route to refresh it.

Instructor support at a distance

Stuck on a point? An “Ask the instructor” channel is available throughout every course, so access to an instructor is provably there — another AMC training criterion satisfied.

Continuation training — frequently asked questions

Is Human Factors, Fuel Tank Safety and EWIS training mandatory?

Yes. Under EASA Part-145 (point 145.A.30(e) and 145.A.35(d)), certifying and support staff must hold current safety training in Human Factors and safety management, and — where their role requires it — Fuel Tank Safety (CDCCL) and EWIS. Recurrent (continuation) training is refreshed on a cycle not exceeding two years.

Is EASA Part-IS (Information Security) training mandatory?

Yes, for information security. Under Part-IS — Implementing Regulation (EU) 2023/203, Part-IS.I.OR, applicable from 22 February 2026 — Part-145, CAMO and CAO organisations must run an Information Security Management System and ensure their people have the competence to work securely (point IS.I.OR.240(g)). One important difference from Human Factors: Part-IS sets no fixed legal retraining interval — the organisation decides how often awareness training recurs based on its own risk (guidance GM1 IS.I.OR.240(g)), with roughly two years a common industry norm plus event-driven refreshers. Our certificate shows a refresh-due date 24 months after issue to fit that norm. Part-IS is sold as a single Initial or Continuation course (EUR 39.99); it is not part of the two bundles.

Which of these courses apply to me?

It depends on your role. Human Factors (incl. SMS) applies to all Part-145 certifying and support staff. Fuel Tank Safety here comes as a Phase 1 + 2 or a Phase 2 (Detailed) initial course, plus a continuation course - for staff who plan, perform, supervise, inspect or certify maintenance on affected aircraft and their fuel system components, and CAMO staff involved in the management and review of their continuing airworthiness. Staff to whom the appendix assigns Phase 1 alone need awareness training only. EWIS here is Target Groups 1-2 - staff who carry out EWIS maintenance (Group 1) or maintenance inspections on EWIS (Group 2).

Do I need a Part-147 approved provider for this training?

No. Part-147 approval covers only Part-66 basic and type training. Human Factors, Fuel Tank Safety and EWIS continuation training may be delivered by an independent provider — the AMC explicitly allows it. Final acceptance rests with your employing Part-145/CAMO organisation and its competent authority.

Will my employer or AMO accept the certificate?

Each course is mapped clause-by-clause to the relevant AMC (a visible syllabus-coverage table), follows the AMC training criteria, and issues a verifiable certificate carrying a unique ID and the issue and refresh-due dates — exactly what an AMO quality system needs to validate and accept the training.

When does the training need refreshing?

Human Factors, Fuel Tank Safety and EWIS are refreshed on a two-year cycle, so each certificate shows a “Refresh due by” date 24 months after issue. Part-IS sets no fixed interval: your organisation decides, and the same 24-month date is a convention rather than a legal limit. Your certificate history is kept and a refresh is flagged when it is due.

Can I watch the lessons instead of reading them?

Yes. Every chapter of every course has two modes. Read is the full written lesson; Watch is the same chapter as a narrated slide presentation, played like a video, with captions, playback speed from 0.75x to 1.5x and full screen. You can switch between them at any point, and the knowledge checks and the final exam are the same either way.

What is the exam format and pass mark?

Each course is a set of taught lessons with knowledge checks, followed by a multiple-choice final exam. The pass mark is 75%, with unlimited retakes, and your certificate can be downloaded the moment you pass.

What is the difference between the Initial and Continuation courses?

The Initial course is the full first-time syllabus taught in depth. The Continuation course is the shorter refresher for staff already trained — it recaps the essentials and focuses on current emphasis and lessons learned.

How much does it cost?

Each single course is EUR 39.99. Either bundle — the Get Compliant initial pack or the 2-Year Refresh continuation pack (all three subjects) — is EUR 99.99. Payment is by card.

Independent training, mapped to the AMC

There is no approval gate for HF / FTS / EWIS / Part-IS continuation training — the AMC permits independent providers. Every course is mapped clause-by-clause — AMC4 145.A.30(e), Appendix IV (Fuel Tank Safety), AMC 20-22 (EWIS) and IS.I.OR.240(g) / AMC1 and GM1 IS.I.OR.240(g) (Information Security, Part-IS) — via a visible syllabus-coverage table, the traceability your AMO quality system looks for. This training is provided as independent continuation training; final acceptance toward your training obligations rests with your employing Part-145/CAMO organisation and its competent authority. Part66Online is not a Part-147 approved organisation.
