Insulation Rule Still of Concern

Controversy continues to swirl around the FAA’s September 2005 aircraft thermal and acoustic insulation regulations, which went into effect in January. The agency amended the original regulations after discovering that the wording implicated a much broader range of components than intended. But, the National Air Transportation Association said that in many cases compliant parts are not available, “putting operators at risk of having grounded aircraft with no viable options for compliance.” Subsequently NATA has expressed concern relating to existing parts catalogs that contain part numbers that do not comply with the new rule. While new production aircraft compliancy will be ensured by the OEM parts catalogs, many out-of-production models have not been addressed by the rule, according to NATA. “Operators risk enforcement action for operating aircraft with noncompliant replacement insulation.”
