This study was commissioned by Transport Canada (TC) in support of a cooperative regulatory activity between itself, the European Aviation Safety Agency (EASA), and the United States Federal Aviation Administration (FAA) regarding Type III exit access and ease of operation. EASA have formulated a Notice of Proposed Amendment (NPA) and Regulatory Impact Assessment (RIA) under the auspices of a Rulemaking Group (CS 25.040) comprising of members from TC and the FAA and from aircraft operators, aircraft manufacturers, and cabin crew organizations. The subject NPA proposes that CS-25 be amended to require that airplanes should be configured with Automatically Disposable Hatches (ADHs) at Type III exits and with applicability should be to airplanes with a passenger seating capacity of 40 or more. The objective of this report was to address any issues that might affect the selection of 40 passenger seats as the lower limit for installation of ADHs at Type III exits. Therefore, this study considers the safety impact of the proposed regulation should it be applied to airplanes with a passenger seating capacity between 20 and 80. |
