GCAA CAR 21 guidance identifies cabin-layout changes, dynamically tested seat changes, seat-pitch changes, altered seat-to-divider distances, changes affecting evacuation paths, new galleys, toilets and wardrobes, and certain electrically powered galley equipment as examples that can require formal design assessment. That means 'move this seat' or 'add a partition' can be an engineering request even when it looks simple on a rendering.
For UAE-registered aircraft, GCAA guidance on approval / acceptance of changes and repairs says applications should include the design and substantiating data. It specifically notes interior cabin reconfiguration and avionics / in-flight-entertainment upgrading as examples where a complete data package may be required when a UAE-registered aircraft is used as the prototype for a change.
Bella therefore treats renderings, mood boards, cabin-zone plans and material concepts as design information. The appointed approved Design Organisation, OEM / STC holder, maintenance organisation, operator / CAMO and GCAA processes determine the final engineering, compliance evidence and release to service.
- Confirm aircraft registry and accepted type certificate
- Identify existing STCs and approved cabin configuration
- Classify proposed changes with the approved design organisation
- Confirm seat / monument / exit / egress implications
- Confirm material and flammability requirements
- Confirm electrical / CMS / IFE and antenna implications
- Confirm weight-and-balance impact
- Agree responsibility for approved design data
- Agree maintenance / completion-centre scope
- Plan updated records and return-to-service requirements
