UK CAA Part 21J DOA
Where Innovation Takes Flight
When aerospace engineering meets regulatory precision, something remarkable happens. At Morson Praxis, our UK CAA Part 21J Design Organisation Approval (DOA) team doesn’t just navigate the complex world of aircraft modification – we make it look effortless.
Think of us as your aerospace translators, converting brilliant ideas into certifiable reality whilst keeping both feet firmly planted in regulatory compliance.
How We Elevate Your Projects
Our team holds the keys to approved design data packages that span the full spectrum of aerospace modifications. Whether you’re wrestling with major changes that reshape aircraft capabilities or minor repairs that keep operations smooth, we’ve got the authorisation and expertise to deliver:
- Major Changes & Repairs – The big-picture transformations that redefine what’s possible
- Minor Changes & Repairs – The precision touches that perfect performance
- Service Bulletins – Clear guidance that cuts through complexity
- Supplementary Type Certificates (STCs) – Your passport to enhanced capabilities
Obsolescence Solutions – Because sometimes the best way forward is finding a brilliant alternative
Our Technical Canvas
Our Scope of Approval reads like a wish list for aerospace innovation:
- Avionics – The brain behind the operation
- Cabin Systems – Where passenger experience meets engineering excellence
- Electrical Systems – The neural network that powers performance
- Environmental Control Systems – Keeping conditions perfect at 30,000 feet
- Structures – The backbone that makes it all possible
From elegantly simple repair schemes to complex special mission aircraft modifications, we bridge the gap between ambitious vision and regulatory reality.
Aircraft We Approve For
Our certification spans the aerospace spectrum:
- Small & Large Fixed Wing Aircraft (Part 23 & Part 25)
- Small & Large Rotorcraft (Part 27 & Part 29)
Whether you’re working with nimble regional aircraft or commanding long-haul giants, we speak their language fluently.
The Morson Praxis Advantage: Simplicity Through Expertise
Here’s where we get a bit clever (but not show-offy about it). Our combined Part 21J approval and deep aircraft engineering expertise means you get something rare in this industry: a single supplier solution that actually works.
What this means for you:
- Fewer complications in modification programmes
- Minimal internal management headaches
- Faster concept-to-reality timelines
- Quicker response to customer demands
We also operate a global Repair Design Office, offering aircraft surveys, damage assessments, and embodiment programme support. Because sometimes the best engineering solution is one that saves you time, money, and complexity all at once.
Beyond Part 21J: The Full Spectrum
Our aerospace and defence capabilities extend well beyond DOA services. When you work with Morson Praxis, you’re tapping into a comprehensive engineering ecosystem designed to solve complex challenges with uncommon intelligence.
