Public Consultation on proposed Deviation Request UKTSO-C127c.Dev.002

Overview

The UK CAA is consulting on a deviation request to CS-UKTSO in accordance with the provisions of Part 21.A.610.

The proposed deviation relates to CS-UKTSO Amendment 17, UKTSO-C127c, Section 3.1.1, and seeks to amend the pass/fail criteria by defining a load threshold at which the upper torso restraint may contact and apply load to the neck of the Anthropomorphic Test Device (ATD) during the dynamic qualification test specified in SAE AS8049/1B and SAE AS8049C, Section 5.3.9.7.

The proposed Certification Memorandum UK.CM.CS.1001 document provides the full technical detail of the memorandum.

This proposed change is intended to provide a clearly defined acceptance criterion while maintaining compliance with the applicable safety objectives and performance requirements.
