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.
