Date Issued: June 04, 2012
Responsible Office: AIR-100
Description: This advisory circular (AC) describes acceptable methods to test aircraft cabin interior materials when new finishes are used on existing aircraft cabin interior panels, typically performed on supplemental type certificates (STC) or major alterations. This AC applies to materials for self-extinguishing flammability only. This AC does not apply to materials that must meet heat release or smoke emissions,standards established by Title 14 of the Code of Federal Regulations (14 CFR) part 25, Amendment 25-61, and 14 CFR part 121, Amendment 121-289. We, the Federal Aviation Administration (FAA), have written this AC for applicants, offering several methods for demonstrating compliance that may be more cost-effective and less time-consuming than current methods.
