Whenever a modification is considered, the ability to meet all requirements of the applicable Federal Aviation Regulation (FAR) must be verified. For example, this would include the capability to meet requirements such as flammability and flotation. Analysis and/or test data supporting the ability of the new materials and/or configuration to meet the applicable requirements must be submitted with the change documentation.
This document addresses the evaluation of seat pan cushions, secondary components, and ancillary components. Other primary components such as restraint systems and primary structural components are not considered.
