Project CS 12/15 - Amendment to CASR Part 90 - Addition of Safety based requirements for Hardened Cockpit Doors
Project closed 20 October 2015.
Certification considerations complete – no changes to current regulations are being proposed.
The terrorist attacks of 11 September 2001 for the first time used high capacity aircraft as weapons. As a result of these attacks, a raft of security measures were introduced worldwide. One of these measures included a retrospective change to standards for cockpit doors. This change hardened the doors against intrusion by persons and penetration by small arms fire.
The existing aircraft design standards for cockpit doors prior to 2001 never envisioned the door being hardened. The subsequent hardening of these doors had safety consequences affecting standard and emergency procedures, both from within the cockpit and passenger cabin. Principally, assistance from the cabin in times of in-flight pilot incapacitation and escape from the cockpit to the cabin in post-crash situations were made more difficult.
All aspects of aircraft security are the mandate of the Department of Infrastructure, Office of Transport Security. Currently, the Australian requirements for Hardened Cockpit Doors (HCD) are contained in the Aviation Transport Security Regulations (ATSR) 2005. These regulations contain technical standards related to the physical hardening of the door and to security related operations of the aircraft. They do not contain requirements related to the aircraft airworthiness or maintenance which fall under CASA’s mandate.
CASA has inspected a number of HCD installations in aircraft, reviewed third party analyses and aircraft incident and accident history. CASA has concluded that the currently regulations do not ensure that the hardening of cockpit doors have not unintended consequences on the safe operation of transport category aircraft. Thus, some small additional airworthiness requirements are required to mitigate these concerns.
Issue a Notice of Proposed Rule Making (NPRM) with a view to amendment CASR Part 90 to encompass the following requirements:
Control of access to the cockpit by any flightcrew member must be from their stations whilst still being able to directly control the aircraft.
Ensure adequate standards for methods of post-crash escape from the cockpit towards the cabin.
Provide for return-to-base Permissible Unserviceabilities on HCDs.
*The NPRM shall include a note that whilst CASA is monitoring worldwide standards development considering in-flight cockpit access in the case of dual pilot incapacitation, it does not form part of the scope for this regulatory project.
Develop an Advisory Circular for compliance with the regulations related to HCDs based on US Federal Aviation Administration and Transport Canada guidance material
