Cabin Retrofit & STC Modification
The engineering and certification side of interiors — transforming the cabin of an in-service aircraft rather than fitting a new one. Covers seat-map reconfiguration, cabin upgrades, the design and approval of Supplemental Type Certificates (STCs), cabin-component production and the installation/CAMO support that returns the aircraft to service. Specialists such as J&C Aero run dedicated cabin-transformation hubs, while broad MRO/modification houses like Fokker Services Group bundle interior retrofit with heavy maintenance and nose-to-tail upgrade programmes. This is where airlines extend fleet life, rebrand cabins, or add capacity without buying new metal — distinct from the seat/monument product itself and from new-build VVIP completion.
"Mid-life retrofit is a recurring multi-year motion for Gulf majors — Emirates' headline programme to refit hundreds of A380s and 777s with new cabins is one of the largest retrofit campaigns in aviation. Growing GCC MRO capacity (Sanad, Etihad Engineering, Saudia Technic, Qatar engineering) and Vision 2030 / Saudi aviation-cluster localisation goals push more retrofit and STC engineering work into the region rather than overseas."

Why it matters in Gulf aviation
- Mid-life retrofit is a recurring multi-year motion for Gulf majors — Emirates' headline programme to refit hundreds of A380s and 777s with new cabins is one of the largest retrofit campaigns in aviation.
- Growing GCC MRO capacity (Sanad, Etihad Engineering, Saudia Technic, Qatar engineering) is pulling more retrofit and STC engineering work into the region rather than overseas.
- Vision 2030 and Saudi aviation-cluster localisation goals reward in-region certification and installation.
- This is the engineering-and-certification side of interiors: seat-map reconfiguration, cabin upgrades, the design and approval of Supplemental Type Certificates (STCs), cabin-component production and the install/CAMO support that returns the aircraft to service.

Key evaluation criteria for Gulf procurement
- STC ownership/design authority: confirm the supplier can design and hold the Supplemental Type Certificate for the modification.
- Turnkey vs component: distinguish full cabin-transformation programmes from single-component supply.
- CAMO and return-to-service: installation and continuing-airworthiness support that gets the aircraft flying again.
- Fleet fit: experience on the operator's exact A380/777/A350/737 variants.
- Distinct from new-build: this is extending fleet life and rebranding cabins, not the seat/monument product itself or VVIP green-aircraft completion.
