4 Definitions of cosmetic defects, inspection zones and criteria
4.1 Simplified definition of a cosmetic defect Cosmetic defects are deviations from the standard or customized specifications/definitions. They are distinct from a certain distance without additional illumination and/or mirror and according to the definitions thereof within this European standard. Cosmetic defects do not affect fit-form-function as a rule, however in certain extreme cases this might actually be the case e.g. if paint build up impedes fitting. The defects listed encompass any process relevant material. Seller furnished equipment (SFE) or similar status: The supplier is not allowed to approach the airline concerning cosmetic issues or definition changes. Buyer Furnished Equipment (BFE)/Seller Supplied BFE (SSBFE) or similar status: Pickups or points of contention raised by OEM which are disputed between both parties (OEM and supplier or manufacturer) will be submitted to the customer to make the definitive and binding decision for all parties. Any decision has to be documented by the supplier or manufacturer and accompany each individual unit in a conspicuous legible way without causing damage to the part/ parts in question. All parties will adhere to the customer decision until as such times another supersedes it. For SFE, SSBFE and BFE all samples have to be supplied by the supplier and/or the customer to the OEM in order to validate the inspection.
