Modification Or Replacement of Components on Dynamically Certified Seat Systems
This document outlines the engineering evaluation appropriate for modifying or replacing components of a previously certified seat when the certification process is based on qualification to the requirements of AS8049, which includes dynamic testing. The engineering evaluation presented in this document may be used to determine if a modification (including replacement of a component) is a minor change with respect to meeting the dynamic testing requirements described in AS8049.<p>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.<p>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.
According to the SAE seat committe memebrs ARP5497 has not been used by the users becasue further advanced and more useful information is avilable from other sources, e.g., AC25.562-1B. Therefore, during the May 2012 SAE seat committee meeting the memebers of the committee decided to cancel this document.
