Part-IS implementation
EASA Part-IS compliance, made practical
Part-IS is often where aviation teams realise that security, suppliers, evidence and operational ownership need to become more structured. BlockFit helps turn that work into practical responsibilities, workflows and tooling choices that fit real operations.

What Part-IS is
Part-IS is the EASA framework for information security management requirements in aviation. In plain terms, it asks aviation organisations to understand the information, systems, suppliers and workflows that could affect safe operations, then manage that work in a controlled and traceable way.
The point is not to create a separate compliance world. It is to connect the work to the people, systems and supplier follow-up that already exist in the operation.
Who is concerned
BlockFit typically supports aviation teams where operational reality, supplier follow-up and system ownership need to meet compliance work.
- AOC holders
- Business aviation operators
- Flight departments
- Aviation suppliers and service providers
Why documentation alone is not compliance
Compliance stays too theoretical when it lives only in a document set. A policy may say who owns a process, but the daily work still happens in inboxes, spreadsheets, supplier portals and operational tools.
The practical question is whether responsibilities, evidence, incident routes and supplier follow-up are clear enough for people to maintain them when the operation is busy.

Compliance holds up when responsibilities, evidence and follow-up live in the tools your team already uses — not only in a document set.
How BlockFit helps
Translate requirements into practical ownership, routines and evidence.
Map systems, suppliers, data flows and the operational teams that depend on them.
Structure incident workflows so operational, IT and management follow-up is visible.
Build or adapt lightweight registers and trackers when existing tools are not enough.
This approach comes from doing the work: BlockFit has supported a business aviation operator through the technical side of a Part-IS implementation, from structuring the work to selecting the right tooling.
Concretely
What you walk away with
Engagements are built to leave your team with things it can keep using, not a report that ages on a shared drive.
An ownership map
Who owns each process, system and supplier relationship — across operations, IT and management.
A structured evidence set
Evidence organised so it stays findable and maintainable, not rebuilt from scratch each time.
Working incident & supplier flows
Routes for incidents and supplier follow-up that hold up when the operation is busy.
A tooling decision
An independent view on what fits and what to avoid — something your team can actually maintain.
Choosing Part-IS tooling
Tools do not match the workflow when they are bought before the operation is understood. A dedicated “Part-IS tool” can be useful, but buying one too early often adds work instead of removing it.
The right setup depends on the organisation's size, existing systems, supplier landscape and who will keep the registers, actions and evidence current day to day.
BlockFit advises on what fits, what to avoid and why. The advice is independent: no tool is quietly resold as the only answer.
Who you'll work with

François Versmissen
Founder, BlockFit
- FAA-certified flight dispatcher
- EASA Part-IS trained
- BZF-E radiotelephone
- Aviation ops since 2014
You work directly with François Versmissen, founder of BlockFit: a hybrid flight operations and software engineering profile active in aviation operations since 2014.
His background includes flight dispatch, OCC work, flight feasibility, operational engineering, EFB management, crew and FTL monitoring, and PPR, slots and handling coordination across EASA and FAA environments.
He builds operational aviation tools end to end himself, including dispatch and crew management systems, FTL, logbooks, qualifications and issue tracking, with Laravel, React and systems integration work.
BlockFit is not an audit firm and does not certify anything — it helps you build the practical side: ownership, evidence, workflows and tooling that hold up when someone checks.

Part-IS FAQ
Is Part-IS only an IT project?
No. Part-IS touches systems and information security, but the practical work also involves operations, suppliers, responsibilities, evidence and incident workflows. Treating it as a pure IT project usually misses how aviation teams actually work.
Do we need to buy new software for Part-IS?
Not automatically. The right tooling depends on the organisation, existing systems, team size and who will maintain the work day to day. Buying a dedicated tool too early can add work instead of removing it.
Is BlockFit an audit or certification body?
No. BlockFit is not an audit firm and does not certify anything. It works on the implementation side: ownership, evidence, workflows, supplier follow-up and tooling choices that make the practical work manageable.
How does BlockFit work on Part-IS engagements?
BlockFit works directly with the people who run the operation and the systems around it. The work is usually practical and focused: mapping what exists, clarifying owners, structuring evidence, reviewing supplier follow-up and helping choose tools that fit.
Can BlockFit help us choose Part-IS tooling?
Yes. BlockFit can help compare what fits, what to avoid and why, independently and without reselling a tool as the only answer. The goal is a setup your team can actually maintain.
