AD/OXY/15 - Puritan Bennett Oxygen Masks Withdrawal From Service

Overview

The Civil Aviation Regulations 1998, amended by the Civil Aviation Amendment (Enhancing Aviation Infrastructure) Regulations 2006, introduced a specific directive addressing the safety of oxygen systems in aircraft, particularly concerning the Puritan-Bennett Aero Systems Company Series 174290 Constant Flow Airline Portable Oxygen Masks. This legislation was enacted by the Australian Parliament to ensure that the civil aviation sector adheres to stringent safety standards, particularly in relation to life-critical equipment such as passenger oxygen masks. The policy objective behind this directive is to mitigate risks associated with compromised oxygen flow due to design errors, ensuring the safety of passengers during emergency situations. The directive mandates the immediate withdrawal from service of affected oxygen masks and their replacement with approved alternatives, underscoring the importance of maintaining high safety standards within the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 107, mandate the withdrawal from service of certain Puritan-Bennett Aero Systems Company Series 174290 Constant Flow Airline Portable Oxygen Masks. These directives apply to all masks with part numbers 174290-14, 174290-24, 174290-34, 174290-44, and 174290-54, manufactured between 1 September 1992 and 30 August 1996. The requirement is that these specific oxygen masks must be removed from service and replaced with an FAA approved oxygen mask that does not incorporate the part numbers specified in the directive. Furthermore, these particular masks must not be installed on any aircraft. Compliance with these directives is mandated within seven days of the directive becoming effective on 2 July 1997. The directive is applicable nationwide, encompassing all aircraft and operators within the Commonwealth of Australia, ensuring adherence to safety standards and mitigating potential risks associated with the identified design flaw.

Key Provisions

The main operative sections of AD/OXY/15 focus on the removal and replacement of specific Puritan-Bennett oxygen masks (section 1). This directive applies to all Puritan-Bennett Aero Systems Company Series 174290 Constant Flow Airline Portable Oxygen Masks with part numbers 174290-14, 174290-24, 174290-34, 174290-44, and 174290-54, manufactured between 1 September 1992 and 30 August 1996. The directive mandates that these masks be removed from service and replaced with an FAA-approved oxygen mask that does not fall under the specified part numbers and manufacturing date (section 1.1). Additionally, it prohibits the fitting of these masks to any aircraft (section 1.2). Compliance with these requirements is expected within seven days of the directive's effective date, which is 2 July 1997. The obligations imposed by the Civil Aviation Regulations 1998, specifically AD/OXY/15, require aviation operators to identify and remove the specified Puritan-Bennett oxygen masks from their aircraft inventory. Once identified, these masks must be replaced with FAA-approved masks that do not have the affected part numbers and manufacturing dates (section 1.1). Furthermore, any aircraft currently equipped with these oxygen masks must ensure that they are not used, and these masks must not be installed on any aircraft in the future (section 1.2). Operators are required to comply with these directives within the stipulated timeframe to maintain airworthiness and ensure passenger safety. The Act imposes significant obligations on the parties or entities it governs, including the mandatory removal of the specified oxygen masks and their replacement with approved alternatives. Failure to comply with these directives can lead to serious consequences, including potential grounding of aircraft if non-compliant masks are found during inspections. Operators must conduct thorough checks of their oxygen mask inventories to identify and remove any affected masks, ensuring that only approved masks are used on their aircraft. The directive underscores the importance of timely compliance to maintain the high safety standards expected in civil aviation. Any breaches of the AD/OXY/15 directive can result in severe civil and criminal consequences. While the specific penalties are not detailed in the text, non-compliance with airworthiness directives can lead to substantial fines, aircraft grounding, and potential criminal charges for aviation operators. The Civil Aviation Safety Authority (CASA) has the authority to enforce compliance, and repeated or serious breaches can result in significant penalties, including hefty fines and even imprisonment for individuals responsible for ensuring compliance. The seriousness of these potential consequences underscores the importance of adhering to the directive’s requirements.
