This standard defines surfaces on visible components in the aircraft cabin. Surfaces will be considered under the aspects of technical feasibility of the industrial design. This standard is a guideline between airlines, supplier and OEMs with regard to cosmetic issues. This document aims to: a) Provide the supplier 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.
