This document aims to: a) provide the supplier or manufacturer with quality criteria, which need to be met during the production, testing- and quality-inspection-process. b) guide airline-, OEM- and supplier-quality assurance with a description of cosmetic standards for following inspections: — supplier internal QA inspection; — first article inspection; — source inspection; — incoming inspection; — final assembly line, cabin inspection; — customer presentation. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

4.2.3 Zone C Surfaces that require - first “opening up”, e.g. folding, moving or removal of primary or secondarily viewed areas, In order to view the area in question e.g. inside a lavatory mirror cabinet. Can only be viewed using equipment. Areas expected to be perceived by support staff and not passengers. Areas not visible after installation and that have no defined aesthetical surface treatment are still within the parameters of zone C; however still maintaining other requirements e.g. closed edges, fit, form and function etc. Sizes/dimensions of areas/surfaces eligible shall be demonstrated in the technical documentation and require the OEM acceptance. 4.3 Classification of surfaces to be inspected The surfaces to be inspected are classified into three zones (A, B, C). Customers and suppliers shall document at initial technical coordination meeting or functionally similar meeting latest at Critical Design Review (CDR) or functionally similar meeting areas that may be exceptions after installation in the cabin of the aircraft, all other surfaces according to the below zonal prerequisites unless otherwise agreed. For BFE additionally (or similar status): The customer is required to clearly document and inform the OEM and supplier of his expectations regarding classification of surfaces. Figure 2 shows typical areas for the zones, which are applied cross programm i.e. irrelevant of passenger aircraft model.
Cockpit areas (incl freighters) are considered outside of this European standard and need to be defined on demand between OEM, supplier and customer. The exception to this, is furniture, e.g. lavatories or crew rest that share common walls with the cabin. Freighters, currier or crew perceived or frequented areas i.e. cabin linings/furniture are “A” zones, cargo areas are considered outside this classification and need to be defined on demand between OEM, supplier and customer.

Interior parts of monuments which the cabin crew or passenger potentially frequent, perceive or view, e.g. lavatories, crew rest, special monuments, etc. are equally governed by the same zone classifications as for the outside of SFE (or similar status) monuments. Areas covered by other components or monuments will be considered as “C” zones unless, see 4.4. SIST EN 4726:2019
