Document Title: Dynamic Evaluation of Seat Restraint Systems and Occupant Protection on Transport Airplanes
Summary: Change 1 to AC 25.562-1B would remove guidance that allowed certain methods for showing compliance with 14 CFR 25.562(c)(5). These methods were issued in error and have resulted in conditions where the full required range of occupants might not have the same level of head injury protection. They also conflict with existing FAA policy ANM-115-05-14.

Please note that this proposed change affects pages 12, 19, 20, 74, and 75 of AC 25.562-1B. We have posted and are requesting comments on these pages only. For reference, you can find the complete version of AC 25.562-1B (without the changed pages) on the Internet at http://www.faa.gov/regulations_policies/advisory_circulars/.

Please note that as of April 23, we have posted an updated version of the proposed AC. It corrects paragraph numbering errors on pages 20 and 74, and a reference to the related policy on the first page. No changes were made to the technical content
